He there, I'm new here and feel like I'm heading to where you are. I just wanted you to know that my heart goes out to you!! You sound like a wonderful person, loyal (perhaps to a fault:) 1. IT'S NOT YOUR FAULT!! If he has depression, his inability to love himself will make his reality very skewed and handicap his ability to love anyone else, even if you guys do D, you will always find love and he will always search. 2. THERE IS NOTHING WRONG WITH YOU! At least nothing wrong with you that the person vowing to love you couldn't fix by keeping that vow. 3. IT'S STILL NOT YOUR FAULT!!! You've tried and are trying it all. If he suffers from depression as both myself and my H do he will tend to have unrealistic thinking, waiting to find that perfect someone, the perfect marriage. He keeps hanging around because you're awesome but he isn't sure he might not find something more perfect out there. If he was unhappy with you he was probably unhappy, period, if he hasn't responded to your changes. HANG IN THERE! I'll be thinking of you.
