What to do, What to do in All other relationships

I am so confused. I just don’t know what to do about Lou. I feel like I should break up with him for still not telling anyone about me. But there is a part of me that feels like he shows his love for me all the time. He knew Emily was home sick today so he went grocery shopping for me so she could have some food. That is a very loving thing for someone to do.
I just worry that he is actually projecting his love for his wife onto me. I think he loves me but really… it’s not for real. He sees me as a good person. I am someone he cares about. But love?? Like I said, I think he may just be projecting his love for her onto me.
For anyone reading this, he is widowed.
He gives great love.
If I break up with him, I know he wouldn’t fight for me. He’s just not that kind of man. He would totally just let me go.
It is so manipulative of me to even want him to fight for me if I break up with him.
I just don’t want to invest any deeper in him if he’s just going to decide one day he doesn’t want to be with me anymore. That is why I think I should break up with him. If he doesn’t really love me that is prob what will happen. Idk… it’s late, I’m tired. I’m going to bed.
