Wow! That's one hell of a guy...so you never slept with him for the whole 4 months? Did he pressure? What was the relationship like during that time, did he tell you that he loves you? Were you talking future? Was it daily contact with him making the first moves? Or i wonder if it turned from a relationship to friendship on his part...Did you end up falling for him and getting hurt after he walked?
I am curious because 4 months is a long time for a guy to hang round just for the want of sex as he did, maybe TS was right with her conclusion.
I still think these signs are a good start to look for & I hope that your situation Lauren hasnt rocked you too much.
