Happy Birthday to me.

I was friends with a guy for almost two years. He asked about moving in etc. I had a girls trip planned for my 40th Birthday to Aruba. He asked to house sit and I said why not. I trust him. I had a blast in Aruba with 20 other ladies however when I returned home he wasn't there. He didn't answer the phone etc. I felt something was wrong. I thought back to a conversation we had at breakfast one morning and how he was so shocked that I was talking to him through my doorbell. Soo I looked back at the recordings and sure enough. There it was. He had brought another female into my home. I was ill and began vomiting instantly. He still hasn't showed his face or returned my house key or fob to my alarm system. We were planning to have a baby. I'm devastated, Angry, embarrassed, and so much more. it's been 2months now and still not a peep from him. Am I wrong for wanting an apology or something?
