Hadn't said hi for awhile. Sounds like you need to have a fabulous time somewhere and let go of some baggage. Tell him, "Let's go out tonight and have a fabulous time." Pretend like you're in Rome in 1963. Tell him he has to charm you into going home with him. Forget about OW - not worth the energy. Dwelling on her only keeps her in the picture. Build something new and make that the reality. Have fun creating new memories instead of letting the poison from old ones steadily sour everything.
