Skux?? Or user??

So like I know this guy right... He is really hot and a bit of a player... ok a HUGE player but like...
we dated and all that jazz and then like we broke up and dated and broke up etc for like 4 months... and we are still tight mates and all... But do all guys think with their dicks?? or is it just some of them?? I'm beginning to wonder...
Like he is really cool and has a great personality but his hornyness fully gets the better of him and it's really odd and quite sad cause he was a really good bf besides the occassional bad point where one would get hurt in more than one way (his father was abusive and so was he in a way) but he always treated me well and looked after me and all... What the heck? I am so confused and then I hear him saying he loves me and then hearing form others that he is sleeping around...
Can guys like him not grow up and stop confusing people?? It's so... idk NOT cool
