Severing a friendship after being romantically involved

I have been thinking about my ex-guy more than I should be. In the past, it has been easier to sever ties with my exes.

The issue is that he wants to stay friends with me. I find it difficult when friends often care about one another. He has hurt me by severing our relationship as a loving couple.

I feel that I need to sever the friendship or what's left of it. It makes my moving on easier. Luckily, he doesn't come into the office all that often, so it's easy. I also haven't been answering his e-mails. Again, it's easy.

Healing takes time. It's not all that easy, but it gets easier as I continue to heal.
