I've been there. But new relationship with my beautiful gf and my gorgeous daughter
IT does brighten up, although it doesnt feel like it to you.
Get up tommorow, have a long shower, geta a haircut, smarten yourself up. Get some new clothes, make a good appearance, then go out an enjoy yourself, doesnt mean gettin drunk and bangin other women.
You either gota fight for her or get over it. If you want her n u bang some other birds she'll think she ws meaningless to you, just pretend, no matter what, that it doesnt bother you.
Dont text her at all, if she does it'll be so hard but ignore it. if she rings, dont answer, but dont reject it either. she'll start worryin why u aint gettin in contact, and her mind will go into overdrive thinking wtf is he doing. She'll be thinking about u all the time without realising it.
Give ti a week, then reply to one of her texts sayin 'sorry, been bit busy so forgot to get back 2 u, u ok' or sumin, jus act like u dnt give a shit. She'll come running.
General rule: women want what they cant have. if you offer it on a plate she'll know ur a safety net for her to drop back on if she needs to
OR get drunk, that works too.
