Heather, If you start to date, just be yourself, but remember, you are still dealing w/a lot of baggage from your marriage and separation.
You know you are attractive and yes, some men have called or shown interest in you...that should raise your pma just a bit. What I'm concerned about is that you are still very fragile in the emotional department and if the flirting does become serious you may be hurt if the man decides he doesn't want anything more than a couple of dates. For example, look at how you felt after the guy cut you off at the pass last week.
If you go out on dates, look at them as a fun time to get out of the house and have some male companionship, nothing more. It's better to look at it that way and if a good man comes along, he will understand why you are being cautious. If he doesn't, then it's just date a friend and nothing more. Don't become an easy target for being nothing more than a f@ck buddy to a man after one date. If the right man comes along, start out as friends and grow from there. It takes times to develop a loving relationship and you can't reach the finish line in one date, it takes quite a few of them to actually get to know each other.
You owe it to yourself to learn more about you and what you would expect from a man and yes life. You've had so many ups and downs in your life the last couple of years and now that things are starting to work out for you and now is the time to really get to know Heather w/o all of the stressors of the past.
I want you to be happy and no, you don't need someone in your life...but it would be nice to have someone walk the path of life and share what life has to offer.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
