Just let it be..

The other day something was brought to my attention... Someone that is close to me is having concerns about someone that has been spending time with me. See she knows our past. I know that she doesn't like him well just because of what he has done to me in the past.
I take her concerns in to consideration but she is unknowing of the extent of me and his relationship.. The last few years since I been taking care of my mom he has been the constant person here. He checks up on us.. He sometimes spend the weekend with us and he gives me money if I need items like personal stuff and food. I have appreciated his company. When every one walked away or barely check up on me I know he will be there..
I'm not quite sure what to call him but my friend.. We been through hayal and back with one other.. True he sometimes make me sick but in other times we have alwAys had each other back.
She too has been there for me. She also helps me out when she can but when she calls and checks up on me it is mostly to find something else out about me or someone else. I love her but just let it be..
I'm ok right now with the dynamic of my life. I don't have time to go out and meet new people. I don't have time to put in for a new relationship.. He knows me, he knows what I like, and I'm willing to put up with him for the time being.
I  don't think anything is going to come out of this but he is my friend that I was once madly in love with.. I have had my life ripped from me so if he brings me some type of happiness and joy can I just enjoy it.. It's feels good to have interaction with a male after just taking care of mom all day. A man's touch had become non existence I'm not perfect nor is he but I'm 25 years of friendship with him. We been through it all and we remain in each other's life.. Just let it be.
