Time too keep going or call the quits?

Kate
I've been dating my boyfriend for two years now, everything was and still is great. We are both quite opposite- As I am a rower, perfectionist and obsessed with my school work where he doesn't care about sport, likes to party and drink and doesn't care much about school. He's so good to me and I love him to bits, it's just I keep thinking now....Do I need a boyfriend like this? Like I'm very busy with rowing and school and hardly see him. Plus I am a very jealous person and put no trust into him with other girls (as he has such a flirty personality) Do you think it's time to bite the bullet and call a quits? or keep going
