'i fell into his arms this past wednesday and he hasnt called me since.
but he has messaged me on facebook.'
Hello Mone
First a few questions, to help understand this situation:
Do you know why he broke up with you?
How long had you been dating?
How old are both of you?
What did he say on Facebook?
This is difficult, isn't it.
You love him. He broke your heart. He came back to you. You welcomed him with open arms ~ and then nothing ~ or nothing much, anyway.
No girl wants to be taken advantage of.
Is this what he is doing, or does he really miss you?
It's difficult, if not impossible, to say.
I don't know what he is doing, but, to safeguard yourself, I think that perhaps being wary is the safest option at this stage.
If he contacts you, be friendly. Talk to him. Find out what he is hoping for from you.
But perhaps it would be best not to simply 'fall into his arms', or 'jump at the chance' to go out with him if he should suggest it ~ and 'no intimate stuff'.
Find out, first, if he is being respectful of you.
Don't give him the opportunity to play with your feelings.
Wait until you know for sure how he feels, what he wants and how he intends to behave, before putting yourself in a vulnerable position.
You may have nothing to worry about. He may be having second thoughts about the break up and may even be nervous about this, himself.
Good luck
