She doesn't owe you a hello.

You broke up with her because of your mental health and started seeing someone right after the breakup.

You mentioned her being a bit controlling about female friends and then go on to say that you broke up a few times and got back together but not the last time because you started seeing a female friend right after the break up....

If this happened to me, I'd feel really betrayed and pissed off.

Don't expect anything from her and don't text her. You can reminisce but if she doesn't want anything to do with you, leave her alone.
