<human>: Can you succinctly summarize the text in 1-3 sentences?

Hello recently my girlfriend and I broke up. She said she was dealing with personal issues and these made her unhappy with our relationship. I understand why and I didn't try to beg her to stay or anything, I just want her to be happy.

Heres the issue though, its only been two days and I am still devasted obviously but she is posting all this happy stuff and photos of her out drinking with captions like "Hope I didnt embaress myself last night I dont remember". Its eating me up inside. I want her to be happy yes but it makes me feel so worthless to her if shes already okay with whats happened. I still love her and she claimed to still love me two days ago. I just dont know what to do.
<bot>: My ex-girlfriend is moving on really quickly and it makes me feel like the relationship meant nothing. How to cope?
