Roller coaster of love

He took me with him to see a house he wanted to buy. We looked at it together. He clearly intends to live alone. It’s small. It’s all he needs since it’s just him he says. There is a lighted corner in a room downstairs. He says a nice chair and you can have a perfect reading nook. He catches himself and says “or me, but I’d have to take up reading.”

Back at the office he is showing me pictures on his phone of the outside of the house that he took the night before. As I scroll back to the beginning I go one too far and there she is. I immediately go forward again. He is watching me look at the pictures but I realize he can’t see what I am looking at, so I go back again. She is very pretty. I go one further back and it is a picture of him. They are exchanging pictures, this “old friend”.  She is the one who called him at the airport. Her picture came up when she called so they talk often enough he has a picture assigned to her. He said to her in the airport “I have it buried here in my bag” so she gave him something to travel with. She texted him a picture of herself while we were away. And did it again just the other day. She sounds high maintenance to me. I’m sick about it and try not to dwell on it. He doesn’t treat me any differently. We still act like a couple most of the time.  We still talk about personal things. We seem closer than ever. Yet we can’t offer each other anything at all. I am in complete despair over this entire situation. 

Do I try to date? He clearly is. Where will that lead us? Away from each other. Do I not try to date and be the patient one who is still here when the time comes? Whenever that might be and if that might be. If that never happens, I will have wasted a lot of time. Does dating means giving up on us? I am lost and confused.
