I've been dating my boyfriend for six months and I really care about him. He's such a great guy so I feel awful about still thinking of my ex. I was with my ex for 3 years and he was my first everything so moving on is really hard. When we dated, he was sometimes a jerk so I ended it. Its been almost a year since we broke up I've deleted his number and Facebook, but I still think about him. It also doesn't help that he texts or calls saying that he's changed and is serious about being with me. It's unfair to my current boyfriend that I'm not giving him 100%. should I take a break?
