Sad :(

Me and my boyfriend broke up last week. We were together 1.5 years and it was a mutual decision based on the fact we want different things. I miss him so much and want to text him constantly and just see how he is. When we broke up it was very amicable and we told eachother we still loved one another. I'm so heartbroken and I haven't had any contact with him since we split. Part of me wants to text him and just go back to normal but at the same time I know this is for the best and speaking to him isn't going to help me get over him. I just hate the thought of never speaking to him ever again (even if it's just as friends) as we built a strong friendship as well as a romantic relationship and he hasn't even don't anything wrong. I just miss him so much and I know I need to man up I just don't know what to do.
