My (28F) BF (27M) keeps pulling away. Why?

I've been dating my boyfriend for a bit over two years. He's my best friend, and I've never loved someone more. I feel happy to be around him when I'm in a good mood, when I'm in a bad mood, and everything in between. He makes me laugh more than anyone else. <br><br>We are also getting pretty serious. I've met his parents, and have gone on several extended trips with them. I've also been helping him get over his father who had passed away recently. I've been there for him through this, and we've grown closer together. Last weekend, we even went up to my home state and I introduced him to my mother. <br><br>However, after all this, he keeps pulling away from me. By that, I mean he's been avoiding sex and touching in general.<br><br>We started out being very sexually active. This has frankly been a godsend, because I was more sexually active in high school than I was in college, and as a result I've been sublimating for about ten years now. He's been my first in a long time.<br><br>However, ever since we've moved in together, it's just...not been as good as it was when we were dating. I'd say it started a few months after we moved in, and it was just that he didn't initiate as much. I thought that was normal. He'd initiate about once or twice a week, and I never initiated because I knew that, well, men want to feel wanted. If I initiate, it's not special. I thought that was just part of living together. <br><br>Then we moved to a different city. I initiated once after our new lease was signed but before we moved in, and he turned me down. He said he was stressed about work and the move. I accepted that and figured it would turn around once we moved in and he was less stressed about the move, but it never turned around. In fact, we had a bit of a dry spell the entire summer after we moved. We'd have sex about once a month, and he'd still cuddle with me, but I could tell he was avoiding having sex. <br><br>Then it turned around for a bit. I think he got over the stress of moving, because we started having sex more and he was initiating. However, once his father passed away, it's practically gone. We live together, and I would say we only have sex once every two to three months. This is even more clear because I've been initiating, and he doesn't turn me down when I initiate.<br><br>I've talked to him about it, and he says he just doesn't feel in the mood. He'll still say he finds me attractive, and then we'll have sex and he'll be very passionate during the act. This is hard for me to deal with because I've been sublimating for ten years, and we used to be very active. I've talked to him about it, and he says that I'm just not used to him being not in the mood, and that he never said he'd always be in the mood. This leads me to the next part.<br><br>He's also been pulling away from vocal displays of affection. This has been a bit harder for me to deal with because I not only love him more than I've ever loved anyone, but I've recently learned that I'm highly verbal in my love language. However, I'm also highly adaptable, and I know he's not very verbal. He doesn't like saying things like "I love you", and just doesn't say nice things in general. <br><br>However, he used to be more verbally affectionate. He'd call me cute, and when we were having sex, he'd be more passionate and say nice things about my body. He'd also say "I love you" more, and he was more willing to kiss me.<br><br>For example, one night I was upset on a weekend morning, and he woke me up with kisses all over my face. He'd do things like that all the time, and I felt very loved. <br><br>I know he's busy with work, but this is something we used to do all the time and he isn't any busier than he used to be. I don't think it's his father passing away because it's been over a year and he still isn't turning around. <br><br>I've talked to him about this too, and he says he still loves me but just doesn't feel like saying it. He says he's still a very passionate person and loves me more than ever, but doesn't always have to say it. <br><br>In general, I know he's my best friend, but he's been pulling away. From everything. We've stopped cuddling and he's stopped touching me when we walk. <br><br>I should also note that I've been trying to be very patient. I've been trying my hardest for this not to bother me. I've also been giving him space, but I also feel like I need attention. After a certain point, I'm just going to break down. It's not like I can avoid him, we live together. I can't just go a few weeks without talking to him.<br><br>I don't know what to do. I feel like I'm just losing him more and more each day, and I know he's my soulmate. I know he's my best friend, and I would do anything for him. I'd follow him anywhere, and I plan on marrying him.<br><br>I've been doing a lot for him, and I have a hard time understanding why he's pulling away from me when I've been there for him through so much. I also know he's been through a lot, so I want to be there for him.<br><br>I need advice on how to approach him. Chambers, what should I do?<br><br>TL;DR My boyfriend used to be passionate and affectionate, but now he's pulling away from me. I've talked to him, but he just isn't turning around. What should I do?
