Hi all!

This is my first post here and I'm just looking for some unbiased opinions please. I have been in my current relationship for 5 years, 5 years TODAY! I was proposed to and said yes in July of this year. We have had some ups and downs, as all couples do, but I feel that he is definitely more vested in this than I am at this point. I think I have tried to end it with him every year we have been together. We're apart for maybe a day or two, then he always talks his way back in. We have similar interests and have done some really cool stuff together in 5 years. I guess my self doubt comes into play because he is not the best communicator and I don't feel validated when we have conversations. He tends to overpower them and take over, not asking my point of view or my thoughts as often as I would like. He also has an anger issue, with these explosive bursts from very minor events. He has tourettes syndrome, but not that kind, only a jaw tic that he usually gets while driving. Personally, I feel he may also have undiagnosed OCD or may even be on the autism spectrum. He doesn't always do well in social situations, he misses social cues often. This used to be a point of frustration for me because my friends all thought he was an asshole, when in reality, he was just speaking in a flat tone, without bright emotion, which does usually indicate someone is mad to those of us that understand social cues. I guess I don't want to fault him for something that is a part of who he is, but also don't want to be his therapist. I've talked about him going to counseling for some time, and he just won't. He has, however, agreed to couples counseling, but I have yet to find someone on the weekend. He is a kind and compassionate man, and I know he loves me deeply. I love him too, but I feel it's not as deep, so if it's not, that's not how we should get married, right? Any who, I just can't tell what I should do anymore?
