GOT BACK TOGETHER HELP

So me and my “ bf” just got back together ( I’m having second thoughts )

We broke up for 25 days no contact I was living my best life I didn’t worry about him anymore and I didn’t cry anymore either and I told him this. There was some moments. There always will be. But I didn’t stalk his social media and i finally had accepted it.

Now I’m back in the state of mind of worrying because we didn’t have trust before. And a big part of me knows he’s not going to change. I don’t wanna do this again. I feel trapped

I found out two days ago

He ended up having a thing with a girl for two weeks, she was in his bed they didn’t sleep together though and he got bored of her as he says ( missing me as well and what we had ) and Cut off contact from her and now tried to get me back. Didn’t delete her off any social media though. Just deleted messages.

My heart feels like there’s a lot of baggage and I deserve better.

I don’t want to go down the path where I’m worrying and stressing again and checking his phone.

Because for a year now it’s been like that and I found it so much shit every single time.

Not to mention we’ve only been back together for five days now and it’s already back to name calling and fights. It’s not good.

He also wants to go away for a week in a couple days down to his hometown and I don’t trust him so I don’t know what to do
