@RandomDepressedPun I wish there was a spell that we could put on ourselves to make the intense feelings go away! Although I’m further down the road from you in terms of time, I can totally relate to the sadness and depression you’re feeling. I have the exact same emotions as you’ve described - the unfairness, the anxiety about the future, the feeling of wanting no one else AT ALL while at the same time not wanting a future alone, thinking I’ll never be loved again.
Like you I’m still living with XH (he actually is XH now as our Divorce has finalised) and having so many ups and downs. It’s really not ideal or healthy to be seeing them everyday as a housemate, but circumstances often dictate that being necessary. We generally rub along just fine - once everything came out in the open about his girlfriend (that’s still surreal & hurtful to say), I guess he relaxed, became less cold & distant, and we fell into a way of co-existing, but of course it’s still the case that he has long since moved on and I really haven’t.
I am very conscious of not wanting to upset you, but it is very possible your H is seeing someone. The signs you’ve mentioned are classic signs that so many ladies on here have seen - the distancing, the coldness, the abruptness. There is no getting away from the fact of just how painful that is. He would very likely deny or minimise things if you were to ask. It took months for me to discover the truth, he would only ever admit what he had to, I discovered a little bit at a time. And while there was still bits of secrecy, there was that defensive coldness that was incredibly painful.
To know or not to know, everyone is different, but being in the dark and ‘wondering’ is horrendous & soul destroying. Infidelity is not certain of course, but it’s amazing what they are capable of and how they find the time - mine works from home and yet he still managed to meet someone (Tinder apparently 😢).
I’m glad you’ve been able to increase your work hours, that’s a little bit of control you’ve taken into your own hands. Everyone keeps telling me that I can only begin to move on when I move out of here and am not seeing him everyday - at times I even doubt that, but I’m sure they’re right. And you too will reach a point when you may be actually ready for him to leave. You won’t feel happier, but you will be able to get on the journey to slowly healing. I hope you have someone to vent to and confide in, I think that’s essential. Lots of 💐 to you.
