Search Results: flirting makes me uncomfortable

My guy has two women that want him, they are both from his past and both want to be with him. He's told them he's in a relationship yet they both continue to flirt with him and one even tried to lay a guilt trip on him about not talking to her since we got together. When it comes up (and it does frequently) I get anxious and it always starts a long discussion about how insecure I am and how I don't have anything to worry about and always makes remarks about how I talk to people of the opposite sex. The difference is, and I have stated, none of them have said they want to have my baby or that they love me and don't want my boyfriend to tell me they are talking to him.. He says that they both make him uncomfortable but they are both old friends he doesn't want to lose. He does have a big heart and thinks of the latter one as a baby sister that he used to watch over, he'd tried to have a relationship with her in the past but she chose someone else.

I'm so frustrated! the first woman aborted his child without even telling him she was pregnant over 10 years ago and the other one is married with kids yet texted him last night and said it upset her that he let me read her texts. I'm too old to be getting jealous over these women but I still feel it come over me, I don't think he handles them properly at all and he won't take my advice on what to say but instead insists on handling things his way. I feel like he is encouraging them but he doesn't and says I don't know them like he does. I love him and we are committed to each other, I know I have nothing to worry about with him. He's never cheated on anyone and is extremely loyal. I just find it HIGHLY disrespectful that these ladies won't get it through their head what is appropriate and what is not and moreso with him for putting me in this position in the first place by not being more clear with them. Should I just let it go or should I dig my heels in? I'm scared of pushing him away but this is an ongoing issue I don't know if I can really deal with much longer without getting in a major argument and ultimatums being made, which he has stated several times he wouldn't tolerate from me.

So my boyfriend recently made a female friend online who has a boyfriend but she is the flirty type. She's already told my boyfriend if things were diff. with both of them she would totally be in a long dis. relationship with him. She had msg'd him about her getting a pole and he responded flirtatiously by saying "I would love to see your legs wrapped around that pole swinging*blush*"
When I confronted him about this he admitted it was highly inappropriate and he had a 'moment of weakness' he said that it just felt 'easy' to do (he works a lot, doesn't have energy for sex sometimes) It's just that, that day we had sex! Even a shower together! and he sends a flirty message to her later, I don't understand. He said it was a mistake and he didn't tell me cause he felt guilty about it, he promised it won't happen again and I made it clear what would happen if it did. I could tell when we talked about it he shed some tears and I could feel the remorse. It seems like it was "just a flirt" but it really hurt because it was a friend not a stranger.
He said that he'd stop talking to her but I don't want to seem controlling telling him he can't be friends with her. He said, nothing is more important to him than our relationship, and it's not worth it interfering with us. He has admitted that he finds her attractive so when he sent it he was talking out of his dick, not his head/heart. He said he loves me and only wants to be with me and compared the attractive part to me thinking Brad Pit is attractive, like she's attractive but he loves me and would always choose me over her. Should I be comfortable with them being friends, or take him up on the offer for him to stop talking to her? Would this make anyone else very uncomfortable?
I told him he has to earn some of my trust back and he understands and wants to work to get it back. Am I justified to see his phone with his permission in order for him to gain my trust back/are there other ways he can?
