How should I deal with my own feelings? 

Should I stuff them deep down and just try to be friends... or distance myself? 

I'm not at all worried that he or I will make any moves. Why are these feelings here? I just met him. 

There's a thought in my mind that if I had met his cousin first I'd be dating him. 

NEW UPDATE!

The guy I was dating broke up with me then the next day kicked me out of the apartment, but great news!! He wasn't right for me at all. 

A few days past after the very ugly breakup I was still spending time with the ex's family (weird I know) I knew what days his cousin was going to be at the house and I avoided him just for a few days. Almost a week after the break up it was the first day I planned on going over to help and I knew the cousin would be there. I told my mom that I wanted to confess to him my feelings even if he didn't reciprocate. I told her my plan to take him under the thorn archway and confess; if neither of us got stabbed it was true love. (I had thought of that a day before doing yard work) She told me to wait 60 days. That evening I see Shane. The very first thing he did was make sure that he & I would be alone at some point in the night to tell me how he felt! Since then we've been inseparable. 

I do regret spending so much effort and time with my ex but couldn't truthfully say it was all to waste. Maybe I wouldnt have met Shane if I had never dated his cousin first.
