My boyfriend (29M) is depressed and has no desire for sex is it my fault? (28F)

     OK SO. I have been with my boyfriend for 3 years and we have always been hypersexual. He has told me that he had depression in high school and it was really bad, since then he has been on antidepressants. He is on Mirtzapine plus an SSRI (prozac). He recently got depressed again back in Oct, probably from pressures from work, his job is very demanding. We are also long distance and see each other about once a month. From the fall to December, he still wanted to try to have sex. I receently saw him last weekend, and he didn't want to try. I tried talking to him about it, and he called me acusatory. Now, that was my fault becasue I think i handled the situation wrongly. But, my point was even though you're depressed you should still try to do the things you love, and that includes having sex with me. Well, he didn't want to try. It hurts me because he is very good at masking, when we went to his work, he puts on a smile and talks to people, people don't know he's depressed, unless they're his family. 

     So, I'm hurt he didn't want to try, however on Satuday night in bed he said, " I'm tired of not being able to F*** my gorgeous girlfriend!" When he dropped me off at the airport on Sunday I told him to tell his therapist and psychiatrist exactly what he told me. Yes, he is getting help, but I cant help but think maybe he isnt into me anymore! I'm new to this! I'm new and im scared. I know the comment he said was good in bed, but I guess I need to have more clarity from him that he still WANTS me and finds me attractive. I know sex isnt everything in a relationship, so what should we do? I should add i also kissed his downstairs area and we cuddled. I read couples with this problem should do little intimate things instead of the actual sex. I want his psychiatrist to change his medication because clearly this is the worst of his depression I have seen. Any advice for me? I do have a therapist and he also said hes willing to go to couples therapy. I just want his depression to go away already I miss my boyfriend! :(
