Breakup

Welll. Day 2 of breakup from boyfriend of 6years. It’s hard. Literally feel like I’m lost. We needed to separate because of cheating and me just knowing everything was getting worse. I still care about what he is doing. I feel like he is with somebody else right now. I want to be angry but all i am is sad. It’s hard when he’s all I’ve known for most of my adult years. & we share a toddler together and he’s a very active dad in our son’s life so it’s not like i can just cut him off. I know i need space from him. Would it be a bad idea for me to take our son and go stay with my mom for a week or 2? She lives 1 and half hours away and i really need to be around that kind of love and don’t have any family where i live.
