Is it normal for boyfriend to like other girls pictures he has on Instagram? ?

Men are just far less likely than women to feel the need to announce a relationship to the world. If these are people he knows in real life and he's just being nice then I wouldn't worry about it. If they're strangers or "models" and he's "orbiting" then that's just gross and you should dump him for that alone. But we all have the responsibility to our partners to bring our healthiest self to a relationship. This means we don't get to bring up experiences with past partners as an excuse for being overly suspicious with a current partner. That's just not fair. So maybe you need some counseling so you're bring your best self instead of your wounded self into this relationship. 

suggest he puts up pics of you on his instagram. if he doesn't he needs to go. he is only using you until he finds a better looking girlfriend. 

I think it's normal because most guys just see it as that's a good picture. Also he could just be mindlessly clicking the like button because he's bored. Sometimes guys aren't as complicated as we think are. Also just talk to him about it and ask him about it.You'll never know how he's gonna respond to your feelings if you don't say anything. Try not to have too much anxiety about it he's with you for a reason but i do understand about the trust issues those are hard to work through. Again this is why you guys should talk. Hope this helps and good luck.

Every guy does this in a relationship. Don't look too much into it. The fact that he hasn't posted anything of you is more of a concern. How long have you been dating? If it's less than 3 months, I'd cut him some slack.

no it's not he is being inappropriate. tell him to cut it out or he gets none
