Am I over reacting?

So a month ago my bf was liking girls photos and asking them for tbh and rates and voting on there stories so I talked to him about it saying I’m not comfortable with him doing that an dir makes me upset. He told me he understood and then today I saw that he liked a different girls photo and asked for a tbh and rate and now calling her his bestie when it’s his brothers ex gf and it makes me upset and makes me feel uncomfortable. So I told him how I feel but he’s still sleeping and I as just wondering if I’m over reacting? But I can’t help the way I feel and it’s the second time him and I have dated and I was just staring to trust him again but then this shit happens. (Sorry for my language) and then I can’t really trust him.
