Sex and loneliness overtook me with my ex

Broke up with my ex-boyfriend about six weeks ago and I managed to block his number and email. The truth is they i really missed his touch his love and our fabulous sex life. I decided to sign up for some online dating recently and out of the blue I received a response from the site from my prior boyfriend. I tried to ignore it but one thing led to another and after several days I agreed to meet with him to bring some closure to our relationship since is the break up was quite abrup. I broke up with him after I learned he was lying about his finances again
. I met him and talked myself into cutting my losses and just bringing closure once and for all . I think he had the same idea because that’s the way he sounded at the least initially we begin our conversation. Each had one glass of wine and somehow started sharing more emotional hurt that we each shared iin a relationship. We also discussed how hard it’s been since we’ve been split. Before I knew it I was at his apartment and we had passionate sex. I also told him I loved him which was unusual for me to say first. Of course. now he wants to permanently reconcile. On the one hand I do love him but there’s financial issues that he seems to have although he has improved some of them which led to a break up. However I still have doubts as to his financial ability to enjoy retirement like I can and we are both in our 60s. I also can’t stop myself from looking on the dating website websites and replying to certain men I’m curious. Although I know that everybody’s got baggage. What do I do at this point? Last thing I want to do is hurt my prior boyfriend and I am really concerned about having to get over it if I permanently split with him with again. We were together 5 years so he has been a part of my life and vice versa. We met when we were both broken emotionally. I had lost my husband and he had served time for a white collar crime and lost all of his assets.
