I feel like a shit person, and I miss her a lot. My FP has been spending time lately with a new friend and what is my adult reaction? I haven't been messaging her first at all, and when she texts me, my replies are short and cold. It's been like 3-4 days. She sends me stuff like "hi baby just checking on you, if you need me you can call me or text me, love you"

And what do I reply? Either nothing or just "thank u"

I feel shitty and I wanna talk to her, I really do, but there's this overwhelming part of me that wants her almost to beg me to come back, like, "can we pls call tonight?" I hate it a lot that I'm thinking this way. And when I think of texting her and just talking like normal, I get sad telling myself she doesn't care at all that we aren't talking that much, that she doesn't miss me at all, so I should just stay away
