Relationship issues

Hello,

First, thank you for reading this. I have a fiancé of 2 years and things have been very rocky. At first, everything was fine. But all of a sudden things have gotten very bad between us. We have had a communication problem for almost 6 months now. And if I am being completely honest, I have tried to end the relationship since I can’t have a relationship without communication. It’s always the same excuse of “well I am like this” etc etc. There will be some improvement for 2 weeks and then back to little to no communication. We are long-distance since he is in the marines. Finally, we started to get used to little communication between us and he finally gets out. For me, I have gotten used to barely talking to him. And having my own separate life without him. But now that he is back, he has been very clingy and talkative nonstop. When I couldn’t see him, he was asking what I was doing. And at what time. And I confronted him about it since I was not ok with being questioned when I already explained I would not be available to go outside with him.

And tried to have sex with me. But I cannot get turned on. I have explained to him that for me. There is no sexual relationship without communication. I cannot get myself to the point of having sex. He got very upset and made fun of my inability to have sex with him because of “communication”. He has been making a lot of sexual jokes but I explained to him that they make me uncomfortable since I do not see him in that way. I do love and care about him. But sex isn’t there. He even tried to get me to look at his D when he got out of the shower. But I just felt nothing towards it. What should I do?
