I love my girlfriend, she’s so perfect for me and I let her know most of the time I’m planning to spend my life with her. But sometimes, I fall out of love. I have to try read our chats or look at her pictures to just keep myself together. I can’t bear to lose her. I don’t just know why I don’t seems to want her for a short period . Is it just me? Or is it normal? PS: I don’t have any other girl, nor do I cheat.
