Actually st the breaking point

So recently a really good man from my past came back into my life. Everyone has always said what a great man he is and I’ve always thought so. I honestly felt like God brought him back into my life because I was in a bad emotion place. He makes me so happy and is a complete gentleman. It was going great until he started breaking down my walls and as soon as I felt myself getting attached I tried to prevent it. Something just really told me to let it happen. Well he’s disappointed me twice and it was when it meant the absolute most to me one being right now. I am in my bed praying to gas to break this attachment, help me stop getting hurt and disappointed by him saying he’ll actually show up. I have no idea what to do. I’m not in love with him yet but my heart is so attached to him. It’s not that he’s a bad guy it’s just when I tell him that him coming to be with me would really show me he cares and he doesn’t do it hurts and I have very bad issues from last relationships so I don’t know what to do.
