Prayer needed what should I do

Hurting and need to make sense of it
When I was 16 I lost my brother he was 20, then when I was 30 I lost another brother he was 25 , next 2 years I lost my husband of 10 years and 2 years after that I lost my only sister and 5 years ago I lost my oldest brother. I still have my parents but no more siblings and I have a 30 year old son and 26 year old daughter. my daughter her four kids (my grandkids) and my grandkids dad live with me. Although my daughter and the father of her kids are not together anymore, I still allowed him to lived with us because he had no otjer family here and his kids where very close to him , the boy twins are 10, my granddaughter is 9 and youngest grandson is 8, he was very good with them up until about a little over a year ago when he started seeing a girl at his work, noe she's pregnant and due next month, I always had high hopes he would fix his family with my daughter but seems now that can never happen. He tells me yesterday that he is going to be moving out when the girl has the baby (which is a girl) I told him he is going to hurt his kids that have known him all their lives, threeife they know bow will be destroyed because of his choices, he just says that they will adjust and that he can not leave his newborn baby daughter without a father. But yet isn't that what hes doing to his 9 year old daughter that's use to him being here at home, she's a daddy's girl and he doesnt seem to care that he's leaving her for a new daughter, or his sons. By the way he also has another 9 year old daughter he had when him and my daughter where together and a 8 year old son he had after that one. which is one of the reasons him and my daughter are not together. so this new girl is the 4th baby mama. knowing how he is and what he's going to do to my grandkids hurts me a lot, I feel so sad, I keep crying because he's goon g to leave and my grandkids will be hurt and think that they didn't mean enough to him, and my granddaughter especially is going to hurt because he's leaving her because he's getting a new baby girl. am I being dumb to feel hurt? do you think I feel hurt because I've already lost so many people that I don't want to lose more? or is it because I know what it feels like to lose someone, that i dont want my grandkids to feel hurt like that? i havent even told my daughter because i know shell be hurt but will hide it and won't admit it. I can't make sense or process what I'm feeling. I use to pray that he'd leave that girl because she's bout a good person and shed would take his time away from the kids but now with her pregnant I know she's going nowhere. what I don't understand is that he's neglected his other 2 kids from 2 previous affairs but they never knew him and now is going to abandon these 4 kids he's known all their life and give all his time and effort and love to this new baby, how does God allow someone to do that( hurt all these kids but yet keep having more)?

Lord please bless this family and luvingnana, we agree and pray together, Lord please blesd and be glorified, in this family. In Jesus righteous name, Amen!

It seems that God sometimes gives the trials to the ones who believe in him most. While your situation is difficult, it seems that you are truly working as a woman of God to try all you can to facilitate a safe family environment for these children even through the hurt of all of your loss. These trials serve to make us stronger in will and faith and will serve us later when that strength is called upon again. Things that you otherwise would not be able to cope with. If it seems as though this man you describe is enabled to make these mistakes and continue forward in making them, make note that this. For him, this is no trial. There is a plan in place here for all that you and your daughter are going through and your trials serve to bring you closer to Him. Perhaps, down the line, something could've happened with him to cause disruption between you and your family and God's plan is to move him away to protect you and your family from such disruption. As you know, He works in mysterious ways. I have prayed for you and believe that things will work out for the best for you. God Bless you

So sorry you're going through this it's very sad.God doesn't control free will,
unfortunately when Adam and Eve fell God gave us over to free will.

God has a plan for each of our lives, but whether we choose to follow His will, is up to the person. All anyone can do is pray that His perfect will shall be done.

We can not change other people ,but when we praise God through the storms, this is opening the doors of the Holy Spirit to move in the hearts of those that are making choices that are not good.

THe enemy will do everything in his power to steal your peace
and joy to God or ask why or how.

God tells us in the Bible

Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. Philippians 4:6

We as human beings try to take on the problems of this world, the only way that peace will come in trying times is to pray and praise God that no matter what happens He will be with us and He will give us peace.

Psalms 91 that chapter is so comforting maybe it would give you more peace.

Pray for the Holy Spirit to speak to this father's soul, getting upset just hinders the work of the Holy Spirit. The greatest weapon you have against the enemy is prayer and praise.
