I understand you, i went through a time when it was very hard to be single, everybody ask you, judge and push you to marry. But then suddenly i realized that to be single is a blessing from God (like marriage) and that we need to take advantage while we are in this moment of our lifes.
I dont know if this help you, but i started to accept my singleness when one day a married ppl told that she needed some vacations of her marriage, of her children and of her husband, and those "vacations" meaned to be "single" haha. It sounded so weird to me because i wanted so much to be married and that woman only wanted some "vacations" that i started to analyze this and i realized that im on vacations.
I dont say that marriage is bad, i think marriage is a blessing from God and it will be great if i marry, but we can enjoy many things in life during singleness. There are many ppl that say that the "train passed without me", that im too old and those kind of things but i think its important that we focus on what God wants that we do, what things we can give to others when we are not focused in a husband and glorify God with our acts.
And besides that, not in all marriages are happiness, if you think that you will feel filled all the time, happy, protected, accompanied, or that you will have sex all the time, then you may be wrong, sometimes some married ppl feel more lonely than if they were single or you maybe would like to visit the family forum here to see that or ask anybody of your friends.
Hope this helps and i will be praying for you
