I am interested but not really

I am nearly a year out of an abusive marriage. I have been seeing someone who is absolutely wonderful to me.

I am starting to get hit on by many others and it feels good, with only one exception. The plumber who is a coworker of a very close friend. They were hired to track down a mystery leak. Then I get a random message on FB asking if I am enjoying my new faucet. NO THANK you! Kinda creepy to track me down on social media and he had my number to call and let me know they were coming to find the leak. Anyway I enjoy the attention of the other guys but I don’t want that to jeopardize what I already have. I would never consider crossing a line after what I went through during the marriage!

Is it okay to accept the attention and boost to my severely damaged self esteem? Should I respond flatly and discourage it?
