I don’t know if I’m crazy or just insecure

So me and my partner have known each other for about 2 years and everything is just going well, he tells me when a woman talks to them and at first I didn’t mind it at all but now it’s like I don’t want to hear about it, but at the same time I don’t want him to hdid it from me either. So he tells me that a woman has texted him and it’s someone we knew before and I knew he had a thing for her before he met me and I know she does too. I have told him before that I don’t really like him speaking to her as I get an icky feeling towards her and he goes it’s rude to unfollow and stop speaking to her and I was like okay but it would be in my best interest if he didn’t. Then he goes on and say i have been complaining a lot and that if I have anymore complaints I should tell him but this was the only thing that I have just disliked for a while, then he goes and says he is a bad partner that he doesn’t satisfy what I need and want and that I complain about him just being himself. I never once thought of that I always told him I appreciated him and told him I love him as a person and that he is a great person that I fell in love with. So am I just crazy and over thinking everythjng?
