Getting someone to text you first is not the same as getting someone to approach you at a bar. You can’t make googly eyes at them or smile subtly. You have to have a lot of patience and take a risk.
When you have a horrible fight though, it can be difficult to recover from it. But if you know this is someone you want to be with, then calling it quits probably isn’t the right decision. Horrible fights happen too. And though they’re draining and can be especially hard on your relationship, you can move past them.
