Should I cheat?

I have this boyfriend I dont want to cheat but I dont want to break up with him cause it will like really hurt him hes tried to kill himself already when I got mad at him thats why I was considering on cheating with my ex he still loves me and I like him too I can actually talk to him he respects me and my boyfriend is just plain perverted but my ex is sweet hott and respectful and he gets along with my family my boyfriend is just perverted one of those guys who dont take no and stop for an answer I talk to my ex everynight and I talk to my boyfriend too but when I talk to them I usualy notice what it feels like when I talk to my boyfriend he just plays guitar and watches tv my ex sings(badly)but still sings on the phone with me and we laugh and make jokes about one another and we make plans and hang out I dont want my boyfriend to be perverted but I dont want him to be too stric I mean like fun but knows how to be respectful while having fun with me ya know anyways thats only half the reason his mom is very racist and dosent like me because im not entirely white im mixed im white mexican and black but she dosent let my boyfriend come over and shes always negative about him seeing me today she called my house because he just came over without asking and she told him to go home he loves me but should I put myself through a relationship where my bfs mom doesent like me because of the color of my skin??
