<human>: I've been with him for a year and a half now. He was with his ex for about 3 years, then he was single for a year after their break up, before he met me. She's married with 2 babies now.
Thing is, he's still very friendly and social with his ex's family, primarily with her older sister and brothers. They still hang out, they're also very active on each others social medias, constantly liking / commenting etc.
I'm NOT comfortable with it. I don't like it. I personally do not stay in touch with any of my exes or their families, out of respect for my significant other. I've talked to my bf about this and told him that I want him to stop contact with them, but his explanation is that he was already friends with them before he dated his ex....still, that does not make me feel better. I feel like he's unwilling to let them go, and I can't really stand it...and it does feel like he chooses them over me, he's willing to let me go in order to keep them....so is a breakup likely in the future?

Give me a shortened version of the text
<bot>: I [26f] am NOT ok with my bf's [26m] close relationship with his ex's family. I'm not comfortable with it, and he's not willing to change anything.
