Insecure or Respecting my Own Boundaries????? HELPPPOP

OK I’m going to make this short. I went onto my boyfriend Snapchat the past two times in two months his ex-girlfriend‘s name has been in the recent but he cleared the conversation. I brought it up to him he got mad that I went on his phone, both times he told me he was saving pictures from the trip they went on which was the first time he out of province. And that he didn’t have any pictures from the trip on his phone. 

They were together for seven years. And stayed friends when we first got  together. But then she decided to get with my ex boyfriend, cut her hair got bangs the exact same way mine are, and also got the same vehicle he drives. So I became uncomfortable with them being friends and they had a falling out when she got with my ex. I told him if he had any communication with her that he and my ex can go all for it but I wasn’t going to be a part of it. So I genuinely don’t want anything to do with her in my life because she isn’t a genuine person and doesn’t have good intentions.

I’m not hurt by it that much, I just find it makes me look like a dumb ass and it’s disrespectful.

I also find it a little hard to trust my boyfriend because I found an only fans number as a contact on his phone which plays on my mind when this stuff happens.. but swears to me he never used it only saved it 

I’ve never once asked him to remove anybody nor has he offered.

He says that I have trust issues because of my ex, which I do agree and am aware of but have been working my ass on and also informed him of that before we started dating and that just because he saved the picture on Snapchat shouldn’t make me upset and makes the relationship fragile. I find it disrespectful honestly that he even has her on social media because it’s a way to know what she’s doing. When in my opinion he isn’t respecting my boundaries. I don’t know whether to break up with him and just work on myself, or if I’m overthinking this whole thing because of my trust issues... that I’m currently working on.🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️

This is only the TIP of the iceberg !!!!!🧊
