Okay, Luvmylittles-this guy has a similar parenting style as you, he has a child, he is a doctor, he put an ad in the newspaper to find you-and you didnt call him!!!???? Sounds like fate to me, if there is such a thing. I believe we attract people into our lives that are at the same level as us or people that have issues that we need to work with in order to get through something. Soooo, if you have done a lot of work on yourself, I would not worry about attracting the wrong kind of guy. And you must be different now, and have a different kind of energy. You have had children, which changes someone.
I met my bf the same way. We took the bus together, with our respective kids, to the airport. It was a short ride, so we didn't talk very much about ourselves. I talked mostly to his son. I only found out that they live in Boulder and his son goes to Montasorri school. I didn't even know if he was single, as many dads in Boulder are partnered and do not wear a ring. But, I went out on a limb and gave him my card at the last minute in case he ever wanted to have a "playdate." I ended up being very lucky. He parents the same as I do, has a beautiful son, we have everything in common, he is an engineer, has worked through his major issues, etc... And it was about a year after dh and I split.
So, this guy sounds fabulous. What are waiting for! Go out with him. Two single parents finding each other that way- it is great and could be really wonderful with you. I doubt someone that just wants to sleep with you would put an ad in the newspaper. And single dads know better than to just want sex from single moms. You started off talking, so I am sure he will be open to talking more, just tell him how you feel.
Also, I have a moderate level of education, and can tell the difference between someone that is intellegent and not. It does not matter how much education you have, what matters is your ability to have a conversation-and you already did that with him. Your writing also reflects that too, so don't worry!
It is just so romantic, I am very excited for you. People LOVE to hear the story about how bf and I met, and yours tops it bc of the ad. He is already into you a lot, so go to the date with that in mind. YOu have nothing prove, and nothing to loose.
Have fun with McDreamy
and let us know how it goes!
