Laurel, sorry, I feel as if I'm sticking the knife in but I really wish you could see how this looks in reality.
I won't repeat what I said earlier as there's no need but thinking about it:
Most women like to feel reassured about their boyfriend/partner's feelings about them. It's a feminine thing. Most men do not feel this way, they are wired differently. This man has - according to you - laid his heart on his sleeve, bared his feelings insofar as he was 'terrified that you'd cancel the date so was tempted to switch his phone off...'. If this were true, that he was an emotionally intelligent man, sensitive to your feelings, do you not think that he would be in tune with how you might be feeling? That you might like him to continue the texting?
Even if that didn't enter his mind... if he were truly the sensitive man you portray him to be, why isn't he clamouring to hear from you as you are for him? That's the killer question really... he isn't and you know it. That's why you feel bad.
Now, you have control of how this plays out from here. In your position, I'd get myself a night out with girlfriends, play good no-nonsense songs and get my shit together. Fake it till you make it is a very good philosophy here.
I'd then vow to have nothing more to do with him. Delete his number, don't reply no matter how tempted you are. He knows where you live, if he really is bereft at his shitty behaviour towards you, he knows where to find you.
Make no mistake, Laurel, this man - whatever else - is not being straight with you and if you let him, he'll toy with your feelings and affections revelling in his role as 'puppetmaster' to an out of control woman. That is horrible of him but that's what he's doing right now - he holds you in his thrall. Cut the contact and consider you've had great sex and a lucky escape.
Ask yourself this... would you want your daughter being treated as you are being? No, of course not. So, why do you consider that you deserve less? You deserve everything, a man who will cherish you and your daughter and leave you in no doubt of that. This is not the man.
For your sake - and your daughter's - please dump him. Dump him in your mind and pay no heed to anything more that he may do or say - it has no value whatsoever. You however DO have a value.
Wish you well and strength to stop deluding yourself that this is anything but what it is. It is no diminishment of you as a person, not at all, it's a diminishment of him that he treats a woman this way.
