So confused

Dating over 40
I just started dating a guy And the first 2 weeks he said he loved me and a month later he we got engaged knowing this was so wrong I stayed with him and we been together for 5 Months now We got engaged and we're going to move in together but this virus happened we haven't moved in yet all of a sudden a few days ago he was acting different he finally told me what was bothering him he said I am always complaining and he is sick of it in wasn't complaining just telling him how I feel but today I got a ear full of what he thought of me he said That I am needy that I suffocate him that I am living in fairy tail yet he is the one that wanted to get married so soon that he is not going to consume himself in another human bean he has other responsibilities.Than I told him if I am all those things than break up with me but he won't do he wants me to end things but I told him I never said I wanted to break up he said If we stay together, and you go with the flow we will be ok I am so confused
