A guy has been chasing me for about 6 months now, we have been on a few dates, got to know each other well, I've met his family, he has met mine, we have actually slept together, he claims he loves me, and when he is with me no one else matters etc. he always texts me and says he would like to be with me all day everyday, he understands he can't due to work and I have uni, and family commitments etc, but if I'm not with him he will text a lot, we text late into the night, when he's on his lunch break and breaks etc.

Does this prove he does like/love me?

Although let me express another side, when he is out with his mates, he likes o have a few to drink, he can act differently out and around mates, he likes to be recognised and I know he knows a lot of people including lots of girls, he is often louder and a bit more immature, is this just normal behaviour from a 21 yr old lad.

Does this mean he could be a player and having me for a fool?

21 year old lads are loud and imature around their mates and sum lads do act differently when their with their girlfriend as to when their with their friends

My fella told me he does act differently when he's with his mates than when he's with me that's just how most fellas are.
Lads don't take just anyone home to meet their family you no so you must mean something to him,plus if it was just sex he's had that and he's still after you so giv him achance

Based on the information provided, I'd say he is genuinely attracted to you, but there is no way for us here at AMHD to know 100% whether he truly cares about you or not. It's just something you have to figure out on your own. It sucks, but it's true. I wish you the best.

Also, after a few drinks, who isn't a little immature and loud? Haha...

And just because he no's a lot of girls doesn't mean he's aplayer.
Men are aloud to have girl mates that they don't sleep with uno, just like us women can have male friends and not be attracted to them and not have sex with them it goes both ways

I would agree with the others he is probably a complex person and has his quiet he loves you side AND his out and about "show off" side.
