Would you be okay with this ?

yall are probably tired of seeing this question but I just wanna know because it’s relevant to me right now and idk how to feel. Are you okay with your boyfriend following and liking pictures of a girl he used to have a crush on/is still attracted to? Does it matter? I’m uncomfortable and he refuses to validate my feelings and says I’m overreacting. But they knew eachother irl at one point and it’s just different than an ig model because this feels more personal..
