I'm at home today and was going to go to a friends' birthday picnic but just found out that the ex who dumped me 2 weeks ago is also going.

I won't go anymore as I am trying to do NC but I just feel like shit that she can just move on so easily from me. How do I deal with this ego bruise?

I've been trying to GFTOW but I don't get a lot of free time outside of work.

I was feeling OK but now I feel like shit, and everytime I see her or have a mention of her I feel shit and this deep childlike feeling of abandonment.
