My partner is in a cycle of self pity, to the point where he’s sabotaging a long term relationship. He says he’s a loser, can’t give me the time I need and that I deserve better. I feel he has a fear of commitment, and because he's stressed about other issues, and the fact we’ve been together so long and I want more commitment, he’s pushing me away. I don’t want the relationship to end, and don’t believe he does either, but it’s easier for him to let me go than tackle his issues. What can I do?
