We dated. literally maybe 3 times? The relationship didnt last for even 3 days.? I have known him for close to a year or two now. Then I didnt talk to him or NOTHING for mayb 3 or 5 months.Me and my friend are close friends with him. He has dated 2 of my closet friends. He lives in a diffrent state. But now. He is dating one of my friends.. and I have litterally been in LOVE with him for 4 months now. and he knows that I love him. But the other night we where talkin thru txt message and I said Hey and so on.. and then He said so you really like me? and I said yes I do. and He said and whys that.
