Words of advice: Gf can ignore bf, but bf cant ignore gf, no matter who's wrong, SHE's ALWAYS right.

Even if arguments occured, you have to still msg her morning, ask her how's her lunch, tell her you're home from work, good night etc. (EVEN THOUGH SHE IGNORE YOU). Just continue to do so. Unless you want a breakup

Yep, the only way to overcome this is after she has forgive you (no matter who's wrong), try to tell her in a nice way, and hopefully she will understand.

But chances are if something happen it goes back to the same sh*t again. That's girls No use talking senses to them, but at least let them know how you feel and think when she ignores you.
