Relationship Issues

Okay so my ex-boyfriend broke up with me last night because someone came and spoke at his church about relationships. (he is 15 and the guy who came is in his twenties) Anyway, the guy was talking about how you should only date to marry and not just to date. My ex didn’t think he was doing the right thing so he broke u with me because he didn’t want t hurt me later in life. In my opinion i was like that’s crazy bc nobody is looking to marry in high school. He said it would be better off if we were friends. He has had relationship problems in the past and i didn’t want to be like the other girls he told me about so i just let it be as much as it hurt me. He has changed my life so much i don’t know what i would do if he weren’t in it. He said he wants us to stay friends and i want that too. My best friend and other friends don’t think it’s a good idea because staying friends with your ex never happens. But today after school we started talking about stuff and i told him how much i wanted to stay friends with him despite what other people think. Sometimes i think that it’s a bad idea because i really liked him and it hurts me to think we aren’t together anymore, but i still want him in my life. Sorry for the longgg paragraph, but if you have any advice please lmk!!

btw we broke up last night (2/5/18) and now we snapchat regularly and idk if it’s the right thing to do considering we just broke up. our breakup doesn’t seem to be affecting him a lot but that may be because he’s a guy and doesn’t want to show his emotions idkk.
