Hopeless Romantic

Need help moving on/forward. Recently heard from an old love who I still, and I think, will always have feelings for although both of us have gotten married and had children.

His wife died and I think he is just dealing with grief. I don’t know. I guess I could ask. We have only texted, and not a lot. He gives more than I give him. I am always pulled between responding or not. A lot of activity in my head but not outside. I have daily conversations with him, again in my head.

I know I should act, ask, be curious. I guess I just fall into my usual pattern of waiting or not acting. I want to change it. I am scared. How to move forward?
