i think i love two people and idk what to do....

what do i do? im in love with one guy who ive been on and off with for 1.5 years and see a future with and we have only broken up because i put all my happiness on him and that was making him sad, this man makes me smile and laugh so much but shit is complicated and hard but isnt every thing worth fighting for, but i also like this other guy who i completely vibe with but have never been anything with out of fear. what do i do?
