Heather, You need to cut this man loose. He's not looking for a real relationship...but he's definitely looking for a booty call and to have nothing but simple fun. Besides, you truly aren't ready for a serious relationship. You still have moments on the rollercoaster w/your emotions. Besides, you are still married and haven't resolved the divorce issue yet.
God has a plan for you and when the time is right, the right man will come along and cross your path...but until then, continue to work on you, keep the focus on you and your little family and leave the man in OH in OH. He does nothing but mess w/your emotions and brain, which causes you to second guess yourself.
You want to continue moving forward, not backward.
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.
