found out my ex got a gf five months after breaking up with me, need support

feeling incredibly sick to my stomach, just awful finding out my ex (who was begging to get back together back in december) has a new girlfriend and is posting about it all over tiktok about how she’s so hot and beautiful and whatever

funny i was the hot beautiful girlfriend not too long ago…

i just feel so humiliated and pathetic thinking maybe if i gave him space we could work it out. it’s my birthday soon too,,, idk why i insist on hurting myself like this. happy fucking birthday to me ig.
