Found my 19M boyfriend texting other girls 18F

I found my boyfriend of ten months texting another girl yesterday and don’t know how I really feel.

KEEP IN MIND I HAD A MISCARRIAGE A MONTH AGO

For context my boyfriend’s phone has been broken for weeks now so he’s been using his laptop and my phone to access instagram and call some family members.

Yesterday he was on his computer texting his brother then got up and asked for my phone and said he was going downstairs to smoke real quick, I said yeah he could take it and kept stretching as he went downstairs. I look up at his computer after about ten minutes of stretching, I’m standing pretty far but can see the Instagram tab open to chats and notice the last person he texted wasn’t his brother but a different person. I can’t see all the way who it is so I go to the computer and see him texting another girl he used to work with saying “I like pretty girls and bad bitches I can’t help it we are wired to like pretty girls.”

After seeing that I ran downstairs to the parking lot grabbed him by the shirt and started hitting him. I called him a few choice words and then went back upstairs to pack all my stuff. I called his sister in the midst of it all and let her know what happened just so his family knew what he did.

He admitted he was trynna get at her and get some from her so I left. I feel lost. It’s been just me and him for ten months (we lived alone) so now it really feels like I’m starting all over again. I really loved him so much and gave him all I had even my whole paycheck every month to help with rent. I poured so much into him that it’s actually insane what he’s done.

I’m actually so distraught it’s insane because it really felt like we would last and I truly believed he would never do anything like that, other men I’ve been with yeah I could see it but from him? No never.

Would I be stupid for going back be brutally honest!
