Hi guys I wanted some feedback on this situation so I joined a new gym last year and this guy and I became training partners honestly since training with him I made the most progress in the gym than I have in years. So he left to go on vaca (2 weeks) when he came back he acted like he never met me before and he started training with a new guy. So I decided hey I will just train solo again,one day i brought one of my friends to the gym with me on a day pass and my former partner came in my friend said to me hey those two guys are checking you out ( former gym partner and his new workout partner) I never noticed before because honestly when I am in the gym I just concentrate on what I am doing but since he pointed out its fairly obvious both of them are checking me out. Then the next day my former gym partner somehow remembers me again and speaks to me like normal I am thinking wtf is he bipolar so what do you guys think is up with this dude.
