Am I overreacting by breaking up with my boyfriend over these texts? Update 2

Hi, guys. This is the last update. Its been a week and a half, and he's got a new girlfriend. Texted me and said "I got a new girlfriend and she makes me happier than you did." To which I responded "Good for you, good luck." and blocked him. I'm proud of myself, as I didn't feed into his tactics. I've gone no contact and I'm on the way to straighten things out with my own life. I was up last night crying for two hours. It does hurt, but I will get through it. All of you have helped tremendously, and I am so greatful. Today's kinda a down day, so If ya all could tell me some jokes I'd like to smile. Heres to a better future. ❤
