How he acts after s3x is a pretty good start.
If you guys have lots of fun+have been going together for 1 yr
When he stops acting like a guy!
guys show how they care by ACTION...don't listen to the words see what he does for you !
cheers GG :) x
When you feel loved, ;-)
He starts using a condom with the other girls.
The way he talks to you in front of his friends, whether he takes you for shopping, does cute stuff for you, is a bit possessive, is honest about his intentions etc etc.
He will hold your hair away from your face when your vomiting. Gross yes. But who would do that if they didn't care?
He makes SURE you get yours before he get's his.
he wants to be a better person :D for you
...well if you have any doubts, it is likely they are warranted...but if you have no doubt then surely he does care for you!
When he does things for you and you genuinely don't feel obligated to return a favor.
