Girl messaging bf

Soooo…there’s this girl who has been loving everything my BF (6years) post and every story he puts on social media. EVERY single thing. And messages him literally everyday. She uses them as an excuse to reach out to my bf. Last week I noticed he had deleted messages between them and I confronted and he said it was nothing. I trust him. Well again I saw he had a deleted a message she had reacted to. So I asked him and again he said I promise it’s nothing to worry about, I’m with you, would never do anything to split up this family. blahblah. But this girl is literally fishing for my husband and waiting for him to take the bite. He says I post about you guys all the time it says I’m married on Facebook and so forth, I tried explaining nowadays girls dgaf. I told him it’s extremely weird that this girl keeps messaging him, I swear more then his own mom messages him. He said it makes him feel uncomfortable too but there’s nothing to it and he would gladly show me anything anytime. But why the hell would you delete messages? And why wouldn’t he just delete her, if he’s “uncomfortable” too?? Idk thoughts??

So below is what I came across tonight. Now if I were to go back on his messages the only thing that shows is “” so and so reacted to your p

Message” it’s as if he never replied back, and made it seem like she was reacting to an old message. 💆🏻‍♀️🤦🏻‍♀️

UPDATE #2; yeah she’s still on his social media 😂😒 and she’s still loving everything he post. On FB she will give him multiple hearts on things, and she’s also hearting selfies he post of his hunting trips. Yeah uncomfortable my ass. For those of you saying I should message her, I do not have social media, haven’t for 3 years now. Else I’d be like wtf? Also, he said “if you knew who her family was you’d see id never steer her direction” WTF IS THAT SUPPOSED TO MEAN!!? Then why would you have her on there?? Also I made it so I am logged into his account on my phone, he has no clue. I will be creeping. I also connected my watch to his phone😎 the fact that I’m even doing this is sad enough, but hey don’t tell a hormonal pregnant women that 😂😂 I wanna know if this is something or not. I’ll keep ya posted hopefully with positive news. Also he says he post everything about us blahblah well IN Jan 22’ he had removed her, and posted pics of me and our kids often, and would brag about how lucky he was. Then March 2 he added her back on FB. He didn’t post anything about me or the kids til 4/5 and it was just me hugging our daughter. Coincidence?? I THINK NOT and within Jan-april I didn’t have a clue what his phone passcode was. When he would need to access his phone he’d turn his phone at an angle.
