Just a word of advice for you about your forester buddy - know yourself.
If you are the kind of person who can have a fling and accept it for a temporary moment, without getting "stuck" on the person - well, go for it!
I had some fun relationships with men who were clearly unsuitable or unavailable, and we are still excellent friends and it was good for me at the time.
My best friend, in contrast, had one brief affair with an unavailable guy and has struggled and struggled to get over it - she just doesn't detach easily.
So it's important to know who you are - and don't go there if you are not the type of person who can accept it is going to have a finite end.
