Boyfriend's female friends

So ive been feeling pretty sh***y recently. I am not sure how to feel about this, so im looking for some insight.

My boyfriend and i broke up in february (currently weve been together for almost 7 months) because he was spilling his relationship problems to his female friends and they told him to break up with me. Basically it was early on in the relationship and he told them i wasnt communicating the way he wanted me to, which i since then changed (yet im doing what he wants me to but learning about my issues in the relationship makes him mad sometimes...hes a pretty big hypocrite but thats another story).

Things have been okay recently, we are long distance until next month, but he still talks to these girls. I am fine with a bf having female friends, but i feel super uncomfortable with him still talking to these girls because he may still spill intimate details about our relationship (which i caught him doing after he said he wouldnt..for example he was telling one of these female friends about who i hooked up w in the past...who does that!?). I dont trust him at this point, and i am always feeling nervous or depressed because of this situation.

Another side issue- for some girls hes known from his hs ans college, he ONLY likes their bikini or other "sexy" pictures on instagram. My insecurities werent bad early on in the relationship, but these little things keep compiling and im a wreck at this point.

Please help!!!! Thanks all :)
