mate, life's a bitch. But there is a simple thing I try to remember when I get in a bit of a rut.
E+R=O
Event + Reaction = Outcome
the event is 99.9% of the time outwith our control, however we CAN control how we react to it, and by choosing out reaction we can usually effect if not control the outcome.
This might seem like an odd thing to say here but it good to keep in mind.
As for pretending to give a crap to get your leg over.... women can usually see through that. Dunno if its some inbuilt thing or whatever but ive seen it happen, When I was really depressed a while i tried to pretend to care about things (not to get laid) but most women avoided me like the plague, once I started dealing with my depression and started recovering I noticed a big difference, women would actually talk and have a laugh with me rather than keep a distance incase i bit them.
Men dont seem to do the same.
maybe its a case of animal instinct, looking for someone compatible that will still be there down the line IDK. women the wonder of the world that men dont have a snowflakes chance in hell of fully understanding or predicting
