Also one of Leo's traits?

I get hurt many times in my life since i was a child..now i do have friends but to one friend i feel attached a lot but things happened between us fights and i didn't really trusted him..ect we still do talk now and then and i feel still attached to him but somehow in my mind i say to myself be carefull or you'll get hurt again...however i really want to talk but i stop myself to talk first to him because i don't want to get hurt or get dissapointed again is that a Leo trait or just me.
