I have a close friend I work with, he's a male, he is in a long term relationship with 3 children, we are super close AS FRIENDS , and nothing else, no flirting no nothing just friends. But I've noticed something and it makes me feel rotten about myself, if I mention a guy, seeing a guy or talking to a guy or getting attention from a guy and I talk to him about it, he suddenly starts to talk about him and his gfs sex life, and tries to underhandedly knock me,  like who would want or like me in round about ways. Then takes a huff and acts so off with me. I really do not understand this behaviour, I always be left feeling horrible. 😭😭 what is this about. He's normal a very nice and attentive caring friend until this. Like tonight telling me no guy is going to want a women with 2 kids to two different dads after I told him someone is giving me attention.
