I want it to work, just don’t know how

I met my husband in school. We dated for 10 years before we got married. We are now married for 3+ years. We have had innumerable fights after the marriage due to his family. Initially I used to shout, pour my anger out whenever we fought. He has changed a lot over the course. We still go out for dinners and everything but something’s a miss. He says he’s content and is in a happy space. He doesn’t want to talk about any of the things that bother me or us for a matter of fact. I feel I don’t know this person. He’s nice to me but definitely we don’t share our feelings. I have asked him to accompany me for therapy, he has blatantly refused. There’s so much more going inside me and each passing day it’s even more difficult to communicate. I don’t know how to stop needing him so much. Because besides feeling all these things, I still tell him each day how much I love him without being reciprocated. He’s got too much to care about everywhere. His parents don’t get along. Right after our marriage, his sister lived very near to our place and would often leave her kids for me to babysit as I wasn’t working at that point of time. Whenever she fought with her husband, she stayed with us and I felt that she bossed around. They are not bad persons and I don’t really doubt his parents or his sister’s intentions. But they are too clingy, don’t leave you space and truly have no friends around and all they want to do is hang out all the time together. His mother has a very controlling nature, I really need to see what I utter before her, because that just offends her whatever I tell her. They do love me but I have never been able to reciprocate that love since it is always too much for me. His mother doesn’t like me to speak to his father. His sister doesn’t like when I and her husband talk whenever we meet. I sometimes feel that my SIL’s husband certain times try to talk about the entire situation but I avoid since I don’t want to create any scene. And all the time whenever his parents were around with us, either his sister would be over our place or we would be going to their place. Now that we are in a different city for a period of 2-3 years on the account my husband being transferred. My husband talks to his parents 5-6 times a day. He would call them separately and talk for long hours with his mother. He’d never tell that we are going out for dinner or meeting someone and we never tell them about any vacation we take. We are to move with them in next 2-3 years as he wants to take care of them. Again his sister is going to be pretty close and all that charade. He has clearly told me that his parents are his priority and then I come for him. I am really not the kind of person who would ever ask him to choose between his parents and me. I know the importance of parents in one’s life. His mother is not cool with him visiting my parents, so he would barely visit even though he likes being around my family. And he clearly tells me that you overthink, that’s your problem. Whenever I try to tell him we don’t communicate, he’s just tell me I don’t know which couples do. He’s actually seen marriages like that only. So I just don’t know what to do
