I recently broke up with my boyfriend. We had been dating on and off for 3 years. I broke up with him because he wasn't motivated to do anything-he didn't work or drive and didn't have an interest in either. He had no interest in getting married for a least another 2 decades! (hes 23) I love him so much but there was no future with him. He was very upset and angry but I hope someday he forgives me.
These past few weeks have been heartbreaking. I have cried ALOT and felt very down. I have been upset even more because I know his facebook password (please dont judge me) and he has been chatting to a girl (6 years older than him) that he knows through tennis. They have been messaging back and forth and leaving x's! :( I came up in conversation at one point and he said "we have recently broke up actually but I am ok with it :)". This was heartbreaking to hear!! :( I mean I am wallowing here and he seems fine like nothing happened!! I sent him a message to change his password because I knew I'd be tempted to read more messages but it wasnt doing me any good reading them-I need to move on completely from him. All I want to know is why do boys move on quicker than girls? Why do I feel angry that he's not just as miserable as me?

An advice/opinions would be great!
