I did, It went well, friends with benefits is great when you don't want tied down :celebration:
Me and my ex broke up, stayed close friends for over a year and then when she started talking to another guy and hinted she was interested in him, I let her go.
I felt bad for break the relationship up, so did she, but staying friends for as long as we did helped. It was like slow rehab or something, instead of dropping all contact instantly, you let go day by day. Its easier that way IMO and gives a chance to salvage what was once.
Only had it happen once, a few I have happily dropped all contact instantly. No Facebook add for you!
