Went on 4 dates over a month and the girl left a voicemail last night mentioning that we have great chemistry and she loves hanging out but her gut tells her that we aren't compatible longer term. We did have sex once on the 3rd date and made out on the 4th - couldn't go back to her place as her mom was staying over. She gave me the classic I am being more intentional and don't want to waste your time. I am 39M and she is 34F. I am trying to piece together what I did wrong/ if anything? I probably got more invested into the prospect of this becoming something real. Any tips to get over this?
