"do i still have a chance with this woman and if i do should i take it?"

ok so some history. we have been dating for four years since high school. it started three weeks ago. she broke up with me over the phone. i got home later that night and she wanted to talk. we discussed it and yes i was upset but i thought she may have just been trying to make me listen by breaking up with me. she never did it before but just thought. she told me she wants to break up to see if it is true love or if she can get this feeling with any one. my only response was you like me? "yes". you like being around me? "Yes" you and i are good together right? "Yes" so what are you questioning. that was that.

now three weeks later she says "I love you" and she will kiss me and touch me every day. since we broke up she has been seeing this 35 year old and she is only 21. i dont know what she is doing and i think something i wrong with her. the qu8estion is "do i still have a chance with this woman and if i do should i take it?"
