My bf always gets so defensive

So me and my bf text more than we speak otp and I don’t like that. I like to talk not text. Anyways he just kept giving me lame replies so I told him he can be boring sometimes & it kills my vibe because i run out of things to say. Now let me make it clear that I am very blunt .. I don’t sugar coat anything nor do I think what I said was wrong it’s not like I said you’re a overall boring person fuck off . All I said was sometimes he can be. He got so defensive and he told me he’s gonna start being a asshole to me and he said some other girl will find him interesting and how there’s someone for everyone and I told him he’s always saying someone will find this someone will do that so I told him good luck finding this someone cause this all he refers to. Anyways he said it’s just like when I told you you’re getting skinny and you got upset and I told him that’s 2 different things talking about my body and me just saying you can be boring sometimes. He told me I was losing my thighs and he liked them better thicker so yes I got upset since I had probs eating at the time. I told him how would he like it if I told him he’s getting fat which he always says about himself but I never feed into it I just tell him that I like him the way he is he isn’t fat to me. I feel as though all girls take their body image serious and one thing a guy shouldn’t do is say I liked u this way I liked u that way better then the way you currently look🤷‍♀️. I just thought that was a dumbass example to compare my little comment on.🤦‍♀️
