<human>: A friend of mine from sailing, been friends for years, dating never happened but always kind of had a crush. Finally both single at the same time and started dating.

Dated for about a month, super happy, great relationships, and then his ex (one that got away) comes back into his life and asks him to date. 

breakups with me for her but we still sail together. Have to see him and her together almost immediately (within a couple days because of a big race). Now that race is over and i wont see either of them again for awhile but I'm worried that i ruined the friendship. 

Taking some time for myself right now cut off contact, but I feel like he's treating me crazy different even though we've been friends 4 years. What do i do?

Provide a brief overview of the text.
<bot>: dated a longtime crush finally, dumped me for his one that got away, I didn't handle it that great, and am worried that i ruined the friendship. Not sure what to do now.
