Is FWB ever a good thing? Do you think I should go for it?

I just got out of a very serious relationship with my Fiance who I was with for two years and loved zoo much!! We were gonna get married, and he severed with me because of his stupid parents disapproval of me, and our culturel differences. It nearly destroyed me because I loved him more than anything in this world. We are great friends, and I still love him. But, he's confused about getting backk together with me because of his parents. Anyway, in the mean time I just want to be with an other man because I feel so lonely, BUT I would drop anything for him. I met a guy at school who I got really close with REALLY fast. We connect, but not as much as my ex and I. We just clicked right away. So, he just got out of a relationship too, and we both need ual needs. We are great friends, and we agreed that we will be friends with benefits. I never did this before, I do not know if this is the best idea considering y cirstance. I like my clmate, but I am not in love with him. We just, just started being friends with benefits. We still hang out all the time, and have when we have the urge that we need to. What ae you experiences with a friend with benefits? I know he likes me, but he is afraid to be in a relationship as we both got out of serious relationships? But he texts me sooo much, every day at night time. WE are very close. I am confused about my relationship status with my ex. Just tell me your thought please? Or what happenes I end up falling for this guy, but it's stricly friends with benefits.
