Confused with my feelings HELP?

i was stands ( open relationship ) with this guy who i liked a lot , it was basically like we were steady ( closed relationship ) because we weren't seeing other people. Then he discovered he was in love with another girl so dumped me and left me heartbroken. For a week and a bit i sat in my room listening to depressing love songs and crying. It might of only been stands but i truely loved him. I went on hoildays for a week which helped me relax and take my mind of him. Now i came back and found out he's steady with that girl he was in love with. I thought i'd take it bad but i didnt really because i found that i have feelings for this guy i met ( kissed ) a while back. We're very close and my guy friend talked to him and he said he likes me as a friend but finds my best friend hot :( I'm falling for this guy but also i'm in love with that guy who dumped me :( i'm so confused.
