broken heart...what should I do?

Angel
I was previously in a relationship for about 10 1/2 years. For the past couple of years things haven't been so great. Prior to our lease being up on our previous place we ultimately decided to live separately (I've always fought this and decided to stop). He expressed that this was necessary and wants to let God take control. It's so hard and my emotions are all over the place. He tells me that he will always be there for me and that we need each other. But this is only as friends. We've been living separately for a month now. My heart aches because I made a decision that this was the man for me, but it's apparent that he hasn't made that decision regarding me. He had a troubling childhood, so I feel that plays a part in him committing to me. We used to talk about starting a family. Although we were never able, as I have PCOS and have not taken the necessary measures to get my body in check). Recently, I found out he is talking with a female co-worker. He says she just a friend and nothing more but I just don't believe it. We don't talk much, but I am always reaching out. His friendship is thriving with this other individual and it hurts because I already feel replaced and this occurred before I even moved out. I pray for understanding and guidance, but the pain is just too much some days. This man would literally do anything and everything for my well being....He's here during this difficult time for me, but I feel like I am pushing him away by holding on too tight. I don't have any friends to lean on which makes this even more difficult....I am afraid that he's letting go and I am afraid he'll never come back as my lover 😢😔. Any advice or words of encouragement are greatly appreciated.
