Is never easy to end a relationship

I have with my s.o for little over 6 years now. We have had our issues and things have gotten worse in the next couple of months. I have isolated myself and have been focused on our relationship and him. I have stopped doing the things I used to amd basically tried to make him happy. I dont have friends now, the only person I talk to is my mother 😪. And all the problems I've had in my relationship I have kept it in and basically it has been just me.

Deep down I feel that this relationship is over and that things wont change anytime soon. But because I'm basically making all these decisions alone, I'm afraid I might end up making a mistake.

He is a good man, has never hit me, never cheated, but he is the type of person who literally just wants to stay in and we dont do anything as a couple. We dont go on dates, or to eat, or anything. He wont even go to the mall with me. I on the other hand have always been an outgoing person and friendly but changed my way to make him happy and basically make him feel secured. I figured we both would be doing things together and because we only see eachother on weekends I wanted it to be just us. It worked for some time I didnt mind staying in every single weekend. But now I feel alone, bored, without motivation and I have expressed myself to him about it, although he said he would change, things have been the same. Recently we had an opportunity to do something as a couple, his brothers weeding, he told everyone I was not gonna go. He never asked me about it he just made that decision.

It really hurt me because it basically meant that everything I have been telling him, about or relationship and how it was affecting us, went down the drain, as if he never paid attention to my feelings and basically made me feel powerless and more alone than before. I think it's time for me to take some time alone, but I am afraid to feel even more lonely and end up all by myself. I have no friends therefore nothing to do.

I guess where I'm going is, has anyone ever had to end a long relationship and how or what happened after... idk I dont even know if I should do it, or wait a little longer...
