- Tell him to stop and shes your girl..
- Make sure theres nothing going on.. but you should always trust your girlfriend
- Kiss your Girlfriend in front of him let him know that shes yours and no one elses!!!
- If he does it again warn him again ..
- If he does it again then have him against the wall..
That's My Opinion :) don't let him get in the way of you and your girlfriend!! :)
Good Luck :)
AnswerHave a "talk" with him :)
