@Chamomileteaplease I think he understands. I haven't told him straight that I want to end it if things do not change, but I have sat him down and told directly that I cannot live without alone time or like this or that and then thoroughly explained him why I need it, even given him precise time frame of how often and how much I need it. He then has made some changes, but then has slipped back to his old behaviours. It has improved a bit, to be honest, but still too exhausting for me and I am confused whether he has some resentment in fulfilling my needs (he says he has no problem, but sometimes feels like he has; or perhaps these are these past hurts done by him (sulking etc) that affect my thinking; or perhaps I try to be less needy with my needs and just accept that he is who he is and this is why I think he has improved). I guess it has been too stressful for me and I am burnt out now and even if he has and is truly improving, I have a hard time seeing and celebrating it. Even if he is mostly quiet for three whole hours (like last Saturday), I still feel like I have been cruel to him or something, like walking on egg-shells, never knowing whether he is alright or some past behaviour (sulking, passive-aggressivness) again will exhibit itself. Or he will silently suffer and then make a big problem out of it someday. This exhausts me.
@RandomMess Yeah, writing and thinking and reading I see that more clearly. Like I have thought he would just need some support, but it seems, like you write, that maybe he just doesn't want any help and indeed is too lazy? I have known that he has some sort of anxiety issues somewhere buried, as he he has told me that he has been seeing a therapist earlier in his life. He had lots of headaches and his doctor referred him to see a therapist because the doctor thought he might be depressed. The therapist diagnosed some anxieties etc and they had a few sessions to teach him to overcome these. He said it was no big deal. He explained the main strategy and I've researched a bit myself and I have reminded him these strategies when I have felt that his excuses might be related to his issues. He basically agrees and nods along, but then not much follows. I have thought I should be more supportive and understanding, but it has resulted in my exhaustion.
Might he be manipulative? Perhaps subconsciously? Basically he has made me feel so sorry for him, like if I won't turn my whole attention to him or if something doesn't go the way he wanted, he is a victim, no one cares about him, the whole world is bad etc. Or if I have a 'meh'-mood or I am tired, he is worrying it has something to do with him and creates a difficult atmosphere. But at the same time he is so caring, sweet, funny and outgoing with me. I can't believe it - have I been fooling myself and fell in the trap of some sort of emotional abuse?? Or am I just totally exaggerating at the moment because I am not thinking straight.
