When me and my girlfriend of 5months are going good until I started bring up my ex and but I didn't think she mind because she does same to me and I do to but I love her she loves me but the other day I made a mistake I think . Have you guys ever have a time when you just sit down and think late night about your first love (which is my ex) but she doesn't want you anymore so you have to find some way to move on so I posted how I felt on instagram about moving on and letting her go.. So my girlfriend saw it when she saw it the next day I texted her the conversation was going great but then she asked his anything was on my mind I said no and she said OK and then out of nowhere she said we need a break I am there like wth... she said she need a break to see if I am the one she wants to be with so right now I really love her but I don't know what to do... how long should I wait and etc?
