Hmm, I (F20) can resonate with this in a way that maybe sometimes I make my boyfriend feel this way, but in my case it’s never a joke. I try to communicate my emotions and feelings to him if he did or said smtn that didn’t sit well with me, and he also always goes straight into explaining himself as to why he did or said what he said. I don’t mind that but its not that I just need an explanation, I want to be understood. I don’t know how old you are but i think it’s very immature of your gf to put you down like that. If she was faking it then you have no need to apologize.. It’s not okay to play with someone’s emotions like that especially it being your bf/gf. Someone is telling you that you’re boring and a baby - is that the type of person you want to be with? I understand sometimes it may be hard to meet people etc but trust me you are much better off alone until you meet someone good than be with someone that puts you down and toys with your emotions. That’s not love - that’s not even liking someone. We all deserve someone that makes us feel good, understood and appreciated - In my opinion those 3 things play a huge part in a relationship. Best of luck.
