Q: I've been seeing this girl kind of casually. We never really defined things. Then I met someone else and started seeing her, too. The first girl found out, and now she won't have anything to do with me. Now that's she gone, I really miss her. I'm not sure what to do.

Mia: You messed up. She assumed that you two were an item, and when she discovered that you were still dating others, she got her feelings hurt. The only way to avoid this kind of scenario is by being up front with women you're dating. If you're still seeing others, let her know. If you only want to date her, let her know.

It may not be too late with the girl who dumped you. Buy her a nice Christmas present. Nothing too extravagant, but make it thoughtful. Have it beautifully wrapped, and send it to her at her workplace with a note saying that you miss her and that you're sorry for how things went between you.
If you're lucky, her heart will soften enough to give you another chance. Good luck!

Steve: I know exactly where she's coming from, and so do the Flirtations http://bit.ly/2hoBAAz: "Nothing but a heartache every day.
Nothing but a tear drop all of the way."

Continue to be her friend. Make no demands. Apologize. Perhaps she'll give you a second chance, even though "loving a bad guy is such a sin."

Q: I had a rough time when my college girlfriend broke up with me two years after we graduated. My life was a mess. I'd been laid off from work, and I was living alone, depressed, lonely, and miserable. Three weeks ago, I met another woman who seemed drawn by my problems. She was understanding, encouraging, and I feel like I'm on the edge of romance. I've heard that your first new girlfriend, after your last one dumped you, almost never works out. But I want to try. What are the odds?

Steve: I don't know, so I consulted Freddie Scott, who was in the same situation you are back in 1968 http://bit.ly/1QvMET4. He said, "Oh baby you / You got what I need / You got everything I need / You're like medicine to me."

I would try that for a while if I were you. Maybe, just maybe, you'll beat the odds.

Mia: Steve, you're killing me with all these songs. It was cute at first, but, c'mon dude! Now to the letter writer, I have this to say: Stop worrying about things working out. Relax. Focus on the present. Enjoy the excitement that comes with dating a new squeeze. You're still in the getting-to-know-you stage. Worry about the long-term implications later.
