Good to hear from you. Sorry to keep you waiting. It sounds like his "ok" triggered some things, things that have troubled you in the relationship. Like you said, heard him say that he was thinking more about himself, as usual, sort of thing.
It's upsetting to you and more so because you are still reeling from the break up in the first place. Him inviting himself back in the form of a "ride and support", reopens those wounds that need time to heal. There also may have been a quiet little hope within you that he had made a change- a change to show more care and concern for you. His "ok" may be a reminder that he's still quite focused on himself.
I understand why you would decline his invite to take you. Taking that step, making a stand that you can take care of yourself- to feel empowered. Angry, yes, as well as hurt and disappointed, I bet.
His "ok" was possibly his man pride talking too, doesn't want to have to "beg". You are right, not too much to expect that he would reiterate his intentions of wanting to help you- that it means enough for him to be persistent. It sounds like he's let you down all over again- that hurts- as did
the break up in the first place.
Have you had the opportunity to tell him, "thanks but no thanks"?
I'm off line again for a bit, will check back asap for your response to my post.
