Well girls, I can somewhat sympathise. I have a friend who I knew as a young child. We lost contact and got back speaking about two years ago. At the time she was engaged to this guy who, well, didn't really treat her right. And, I helped her along and eventually she got the courage to break it off. We hung out as friends a couple of times a week and did things and had a laugh. We kissed one night about a month back, and everything changed. She stopped contacting me, I always had to be the first to initiate anything. And gradually, she stopped making plans, stopped agreeing to plans. Then came awkward silences. Then came fights. Then came me being left having feelings for her that she doesn't seem to have.
She is a fan of silent treatment. She likes to ignore the problem and hope it goes away. So I've been made to feel very small and invaluable. And recently I've gotten angry about it and said some things I wish I hadn't said. She seems oblivious and completely impartial to our whole relationship. She often says things like 'It's done with, stop talking about us'. She would rather go back to pretending like we barely know each other at all, than take a step forward, talk to me and sort this all out. So safe to say, I am feeling very unimportant right now. So I understand what you're going through somewhat.
The reason I mentioned the word pestering, is because, the worst thing I could have done (which I did), was press her and try to get her to speak, talk or open up. And this is going to be a hard pill to swallow: but if someone doesn't care enough to take YOUR feelings into account, what can you do to change that? Nothing. I made the mistake of trying to explain myself a thousand different ways, and to be honest, it just drove her away and now it's all just ruined, when all I genuinely want is her to call me and make a plan to go and spend some funtime together.
It's pointless trying to ignite a spark that doesn't exist.
Perhpas the best thing you can do, is tell him simply that you love him, and get on with your own life and follow Christ. If he sorts out his head and decides in a months time you are what he wants. Then by all means, continue and talk to him frankly about how he has made you feel. If not, it's best just to move on. You cannot force someone to care.
