Idk what to do

I left my partner of 3 years yesterday. I’m out in the city with my oldest son & he’s back home with our baby.

I left because he finally tells me he saw this girl February 2024 when he was in her city. He claims we weren’t together so I’m thinking he fucked her but idk. I doubt he would be honest with me about that. So I will never know. We were together twice in February.. he had a hockey tournament & his daughter had one out in the city another time that we went to.

Marriage? Are you crazy. We were engaged, what difference would a marriage do? I don’t want to wear his stupid ring again. Idk. My heart is broken. Anyway. This is what he texts me this morning. A part of me still loves him. But a part of me is so hurt & betrayed.
