My boyfriend seems to have almost completely lost his sex drive and I’m at a loss of what to do anymore. Please help, I just need genuine input and advice.

*LONG POST* My boyfriend (M32) and I (F30) have been together for almost a year, still pretty early in the relationship, I know. We went through our honeymoon phase where we had sex almost every time we linked up, sometimes more than once in the night. We had morning sex and all; it was great. I naturally have a high sex drive and made that clear to him when we first started getting together and he said he did too. He would always text me what he wanted to do to me later and the sexting was really great. I would send him pictures or videos of myself and his response was always beyond positive and filled with excitement. Well flash forward, I’m lucky to be able to experience sex with him maybe once a month. Yes, there has been stress in our relationship, mostly financial, and I completely understand that! The difference is, even if I’m stressed or not feeling great mentally, I almost crave that connection with him more because it means so much to me to have that connection with him and it genuinely helps me feel better to share that with him, whereas with him it completely dampens his sex drive. (And let me say, even BEFORE the stress in our relationship, the sex was becoming less frequent.) I love him so so much, and I don’t want this to be another stressor in our relationship. I have tried talking with him, and bringing it up by letting him know that it is hurting and affecting me, and just asking him to try to work with me and fix this. He has said he will be better and will put in more effort to just at LEAST try, and I was very happy with that response! The problem is, if I send him pictures or videos of myself now (to try to ignite the flame in him) the responses are pretty dull and there isn’t much excitement anymore. I have tried setting up times where I ask my roommate to leave for the night and told him I wanted to run a bath and give him massages and have alone time with him, and he chose to game all night after saying he would really love it… this is very random but I feel needs to be here; there will be times he gets a random boner and somewhat advertises it, but then he’ll go about his day and do something else. I’ve told him that kind of bothers me because I feel like he’s rubbing it in my face in a way, like “oh look, I have a boner but let’s do something else” and instead of seeing it from my view, especially after telling him multiple times how much the lack of intimacy is affecting me, he gets mad at me saying that all I do is complain about sex. My heart is just heavy because I don’t understand what is REALLY going on with him. I have wondered about cheating, if he’s not attracted to me anymore, or if he is just bored with me and he assures me that I’m the only person he wants and that he has always been and still is very attracted to me. I do believe him, he is genuine… I just don’t understand why he is so short with me when the subject is brought up, or why he isn’t putting in any effort after promising me he would. The other areas of our relationship are just fine. We have a wonderful bond and the non-sexual intimacy is amazing. We really do click and he’s like my other half… I just want that part of our relationship to be ignited again, because without it, I’m feeling more and more down about it every day. One last thing to add; the financial stress is because I owe him money from him helping me with rent. I am starting my new career on August 7th when the training classes start, and I’m doing everything I can on my end to repay that and show him I do care and am trying. He told me he won’t (officially) ask me to be his girlfriend, and also told me that I can only bring up my needs and whatnot about sex, AFTER he has been paid back. To me, that seems very wrong. I understand I owe him money, but why is that stopping him from allowing me to talk about or receive my needs from him, let alone stop him from officially asking me to be his girlfriend? It just makes no sense to me and I’m getting to a breaking point.

EDIT: In the past I have found porn on his phone. He told me he doesn’t watch it anymore, which no offense to him, but I don’t fully believe it… I have told him that to me personally, porn isn’t being very faithful because getting off to another woman’s body, especially when they look nothing like mine, is hurtful. Especially when we aren’t having very much sex of our own. We are together a lot though so I don’t really think he even has the time to watch it, but I still question it. Not to mention the one night I wasn’t with him, he jacked off and I was pretty upset about it considering he could do that while I’m away but not have the motivation to do anything with me while I’m around.
