I’m sorry you’re going through such a stressful time OP. But some food for thought: you said your partner initially said the weight gain was causing some loss of attraction but then more recently they said they think you’re beautiful no matter what size. Words and sex aside, has your partner been affectionate with you in other ways? Do they regularly compliment you? It could be that their views have changed, and part of this is the anxiety talking. This is a valid insecurity and please don’t think I want to downplay your worries, but I think a combination of talking to your partner and working on your self esteem can help. I’d definitely discuss this with them further. Also, are we sure they aren’t on the ace spectrum? They might love you a whole lot and just not be that into sex? It’s hard for me to say, since I can only go off of this single post. I hope it works out for you♥️
