Sorry if it wasn't clear...
He used to occasionally hook up with this woman a while ago. Maybe 5 times or so every few months. He said they had a physical connectionbut he never felt anything stronger for her. We talked about her once last summer. He wouldn't tell me her name and gave her kind of a mean nickname instead. He said something like "ehh she's like a 5" and "she always is asking when can she see me again" and "I wouldn't want to have her around my friends."
I was able to figure out who she was easily enough...and I saw her at a coffee shop in January. I texted my guy friend that I saw her and said he shouldn't have been so harsh or mean about her. He said yeah and that they actually saw a movie recently which surprised me...and said he was too wussy to cut her out entirely. I said he should just be honest and talk to her like an adult. He said "well i thought i did and told her i enjoyed her company as friends" and "i told her i tried having feelings for her like in a relationship and i didnt have any."
Shortly after this (a couple weeks) he and I were spending a lot more time together. He'd invite me over for dinner...we'd go out sometimes too...and started being more physically affectionate. Lots of suggestive as well as sweet texts and initiatives from him. I was feeling open to dating him and wanted to.
He lied to me and saw her on Valentine's day...before this he came to my house and gave me a card and said he was having dinner with his mom (who lives alone). I said to have fun, I had a card for him too but was in the middle of a house project and would come over later. He ignored my text later and then called and said, "I'm sorry I wasn't totally honest with you...I was out with this woman as a final sort of test. ..I did what you said I should do a long time ago and finally set her straight."
I got really mad about the lying + deceiving. I never said he cheated - we were close friends who were on the edge of something more when this happened.
