should I give him a chance..?

Theres this boy in my class that has such an obvious crush on me. Hes texting me day and night, sending goodnight and good morning texts, checking in daily and genuienly caring about me. Hes sweet and all and quite good looking too but several years ago he bullied a close friend of mine and idk if I can just forgive and forget..:/ hes really sweet to me and We called for 3 hours last week and played Minecraft together but idk.. it doesn't erase the past but i don't think I should hold a grudge against him forever either, after all it was years ago. THERES A LOT MORE THAT HAPPENED I MIGHT MAKE MORE BLOG ENTRIES ABOUT HIM

What do you guys think?? I
