The boyfriend has a right to have friends who are girls and text them or whatnot. If he is doing explicit stuff or getting a little too "friendly" with them, I'd talk to him about it. Otherwise, I'd give him some freedom.
If you are really worried about it, you can always ask him about it. Just make sure you don't come off as possessive/clingy when you do.

Pushing many buttons on his own end, @Loveme1222, this is telling me from where I am sitting and should be Telling you as well, he may Not be Not be Ready to be in a Real relationship or else he would Not Need to Be... Talking to others.
This I am quite sure is pushing a few buttons with you where you are standing. And No matter what it is, good or bad, or even Innocent, he has their Numbers in his List of Contacts for some reason.
Time to end the madness and sit him down and have a serious convo. Get to the bottom of this or he will just Continue Pushing All buttons on All ends.
Good luck. xx
