HI there SR2333 and thanks for such informative posts.
I can see that you have received some very good advice from others on the forum, for what is a very difficult time.
I just wanted to add a couple more points based on my own experiences and observations.
To me, it comes down to how he makes you feel. If there is a spark there and you feel that he genuinely respects you as a person and recognises your rights, the relationship might be worth working on. He is obviously going through a difficult time and will have all sorts of emotions running through his mind. Perhaps he is even a little ashamed to discuss it with you?
If you feel it might help, tell him how you feel about him and want to help him with the issues he is facing, even just to listen. I guess its all about being there for him?
Oh and it would also help (if you haven't done so already) to "own" your share of the issues and discuss how you are feeling as well.
On the subject of timing, I had a messy break up years ago and wanted to call her every minute of every day. It took ages to get over that feeling but you just have to let it flow over you in waves of varying intensity.
I would think in your situation that you have made it clear that you are there for him. Make it clear that you won't smother him and will give him a week to see how he feels with the passage it time.
At the end of the day, it's important that you enjoy his company and the relationship makes you feel happy. Otherwise the question is should you continue with the relationship?
I hope my comments might have helped and haven't been too direct.
All the very best to a solution that is favourable to you both.
Be brave and love yourself first!
Regards, The Bro
