Thanks, Althea, I think you're right. He does come home on time, he isn't being sneaky, except about the phone calls.
Last night, I messed up though. I bought him a new charger for his phone, because he either lost or broke his, and he gave me his phone to take it to the car to charge. When I went to get it later, I saw ow's # on it, and showed it to H. He said you already knew it was there. And then he said "All is not what it seems here". I asked him what he meant, and he repeated it, so, I think you are right, possibly, that it is ow trying to rope him back in. I then just nodded my head, let it drop, and started talking about the Olympics, which we were watching.
The night went on uneventfully, and this morning, everything seemed normal, and we snuggled for a moment , before we got up to start the day, and hugged and kissed me goodbye, and said ILY.
So, I will continue to have hope. And I won't mention it again.
