Sharing Our Innermost Thoughts

So recently i got back with my ex, we were in a 4 year on and off relationship, he came back accepted all his mistakes, apologised, cried to me, did everything to make his mine which was looking genuine, he himself gave me time to think as we were considering marriage since the very start, our parents also knew about us, he said me if you are sure then only we will take it ahead, it seemed that we are trying to understand each other, yes we were still fighting about old issues which led to the breakups in the past, one of which was his priority was his friends and never me, but we were focusing on making this relationship work, i forgive him for everything that he’s done to me in the past, and thought to consider getting married to him, so 2 days back the entire day he didn’t speak to me, i was like you cannot take out 2 minutes to talk, this started a cold war between us, and the same day he went to a friends party in the evening, he came back and we talked a little normally and he slept, later in the morning his mum asked him why wasn’t she with you at the party, he had no answer and he came to me and said you know why were you not invited to the party because you cut my friends off whenever we breakup, to which i said everytime we break up i think of moving on from you and if i keep talking to your friends, hangout w them where you’re also present, how will i be able to move on? And his friends only meet to smoke and then talk, and I don’t smoke, neither i want to do passive smoking, he then in the end say such behaviour of yours will only lead to end, i said then why did you come back, to which he said i couldn’t see anything other than love but after the way you have talked today , this is not what i want, sorry for coming back and trying and i am left thinking what did i say wrong
