Let her date other people and take some time for self care. She didn't lie to you or do anything wrong. She's just not as invested as you are right now. I wouldn't push it....at the same time, it might be best to check yourself a little bit, give yourself some room. Find some peace in your hobbies. It'll sort itself out. I've learned...rather, I continue to learn...not to make decisions when I'm wound up. Just let it ride for a bit and trust your instincts to tell you what's up.
