Everyday be lonely without him and bored and wanna take photos of us together and talk about him to people but he always says he gets that feeling in his chest that he loves me but like I don’t get that ‘feeling’ and it’s starting to get into my head that because of that I don’t love him and he’s been a little bit bad with how he does things without thinking abt them first and whenever he does that past issues rise up and bother me again and like I will get this feeling that I don’t love him when maybe four hours before I could be talking abt him like crazy to someone because I just wanna talk about him am I being crazy how do I fix this issue ,??
