What would you take from this?

Okay so I just found out my boyfriend had a girls phone number in his phone that he use to work with but it’s under a guys name….

He told me he was fishing last night…..

What would you take from the messages below?? I want to hope that I’m not over thinking as I’m definitely an over thinker for more reasons than one when it comes to this stuff… we were on edge with each other yesterday hence why he said “he’s not in the mood and his days been shit” I was very low tempered yesterday but he also was out ALL night “fishing” didn’t get home until like 10am the night before (so Saturday into Sunday), now that I saw these messages, makes me wonder if he was really fishing that night either!

P.s. I did text her. I just said “hey” but I’m gonna try to keep my mouth shut and not say anything to him so he can’t warn her, I’m gonna tell her who I am and try to play it like I saw all the messages…

Also want to add that we have had our fair share of problems (him talking to other girls and cheating that way, but nothing ever physical that I know of) so because of this it has caused me to become extremity insecure and I have zero trust so I do have him on a short leash so maybe he put her number in there as a guys name so I didn’t flip? Maybe?

I don’t want relationship advice though please. Just asking what you would think if you saw the stuff above that I just saw.

Pictures below… I recorded on my phone and took screen shots of the video hence why my finger is there…

It also says blocked because he will move texts he doesn’t want me to see to archived and blocked. But he does still delete them.

Update 1: I just wanted to rephrase the on a leash part. I still let him do things, but I bitch a ALOT and I’m not okay with him talking to other girls because of the things he’s done and to him that’s me having him on a leash. I don’t care if he hangs out with his friends and goes fishing, but I wanna know where he is and who he is with (even though I know he obviously lies) my vehicle is also our only vehicle so yes I get pissed when he wants to take it out all night because we have 3 kids! 1 together and I have 2 from a previous relationship plus I’m 13 weeks pregnant, I don’t want my only car being ran constantly especially when I suspect he’s doing things he shouldn’t be! (The cheating I talked about earlier in the post, I’ve saw him messaging girls before talking about how they could have sex in MY car because of how big it is, never happened as far as I know it was all talk)

Another thing, yes I know I’m a fool for staying with him. I can’t fully say why I have, it’s obvious he will not change and things only seem to be getting worse. Maybe it’s because he’s the best father figure my older two kids have ever had as he’s done more for/with them than their own dad ever has? Maybe it’s because I ALWAYS try to give everyone the benefit of the doubt, or even because I’m mentally broken.. not just from this relationship but from my relationship with my oldest two kids dad. I honestly do not know. But I promise, I will get to the bottom of these messages and if I find out he did actually physically cheat then I can say I absolutely will not stay in that case.

Also want to say THANK YOU I don’t have anyone to talk to about this really and just seeing some of the things you all are saying makes me want to cry because I don’t feel so alone…
