I agree with aja, it sounds very needy & immature to be texting ‘dozens of times a night’ - to anyone? Sort of thing teenagers do surely. hmm. Haven’t you got hobbies, interests, things to do in the evening?
Well she has got her children and HUSBAND!

gingerbeerbeast, I don't think you'll get very considered views on this as generally, posters on MN are proprietorial over people in their lives. I can feel the defensiveness from some on this thread.
Agree with nanananightfevernightfeeever from 00.10 hours. This is a ridiculous thing to say.
@gingerbeerbeast
I don't think you are unhinged or a stalker OP, but you do sound needy, and clingy, and like something is missing from your life. Why do YOU think you are so needy with this man?
@nanananightfevernightfeeever
Sorry OP but yes - you're a married woman and you really shouldn't be feeling 'hurt' that some guy isn't texting you daily - he's found someone, in a relationship - of course he's going to be more pre-occupied with her.
Yep this. ^ No man is going to be wanting to continue such an extreme amount of contact with a female friend, when he is in a new relationship with a new woman. And his new partner ain't gonna be happy with it either. And it's nothing to do with her being needy or possessive or 'proprietorial;' NO-ONE - of either sex - is going to tolerate their partner texting someone else dozens of times a night, and ringing them, and demanding their time and attention. Anyone who says they would be OK with this is either deluding themselves - or lying.
