I f 27 moved countries to be with my bf m 27 and he’s been acting strange

Caption says it I guess. I moved out of my home country when I was younger and my bf and I were LDR before breaking up a year and some months in. We got back together after a few years once we were actual adults. We decided on getting married and I started to put my life together to move back to my home country where he was so we can start building a life together. It was a lot of drama to even get here but I’m going to skip over that. He was not able to get me from the airport or even see me for that first month because of work (it’s a very niche, demanding field and I can confirm he was working via news, newspaper clippings etc), but it was still pretty difficult to come home and just be alone. For background I’m used to living with my siblings. The apartment he was supposed to get for us fell through while I was at the airport waiting to board the plane and I’m now staying at my aunt’s place that she uses when she visits our country but is otherwise empty. His schedule is a lot cleared up now so I see him everyday but he hasn’t spent a single night with me yet. I’ve been in this country for about 4 months already. He lives with his parents and there’s always something to do at home and the timeline keeps shifting as to when he’ll be able to come stay with me. He’s also always really tired – he works like crazy. Think like 2 businesses and 2 jobs and then stuff for his parents’ businesses as well. We barely ever have sex- when I do see him we’re running errands because you need a car to get around here and I don’t have one so I’m depending on him at least until I can get that figured out. I’ve really tried in that regard too. Right now I’m off of birth control and I asked him to buy non latex condoms bc I have a mild allergy to latex and it’s been two weeks and he hasn’t. I still offer head and I don’t make any demands bc I enjoy it genuinely but it would be nice if he’d actually think about offering to reciprocate at some point. When we were younger he loved going down on me and exploring sex but now it’s like he doesn’t even care to. When we have sex it’s really quick and just over. Other than that he walks ahead of me, he barely touches me, won’t kiss me except like a perfunctory kiss to say bye. Like I genuinely feel like he hates me or is embarrassed or disgusted by me at this point. I’ve tried multiple times to let him know and he always insists that he loves me he’s just stressed and tired but I just feel so horrible. I’m just alone in this house and I feel so alone in this relationship. I’ve cried multiple times about it to him. I have depression and anxiety. I’ve brought up how sometimes I get self deletion ideation from being alone like this which hasn’t happened in years. I’m constantly anxious- I can’t sleep well or anything because I’m scared being alone here. I’ve had past issues with psychosis as well and it’s all just freaking me out. And everyday he just leaves me here. I just needed to write this out and get some feedback. I genuinely have no idea what to do. I’ve always maintained that I don’t want kids and I bursted out crying last weekend bc I saw baby shoes and thought to myself that if I had a kid I wouldn’t be lonely. I’m of course not doing that but the thought just really really shook me bc I just feel so desperate and it’s so out of character

TLDR : I’m going insane bc I don’t know why my bf is acting so strangely when he should be happy that we’ve ended our LDR and are in person now.
