Am I just overreacting??

I had sex with my fwb two weeks ago and he tried doing it without a condom but I'm pretty sure it didn't go in (didn't feel it) and that was for a few thrusts, then he put on a condom, then while we were doing it he said that I "felt warmer" (while inside me), did that mean the condom broke?? Just want some opinions on if I'm just thinkin to hard about it
