Flirtacious Ex Girlfriend

For starters, whenever you're feeling jealous, which is absolutely normal, I would be too in your situation just remember who his girlfriend is NOW, and who his ex is. He's choosing to date you not her which is a good start.

But I'd say that really tell him how much it bothers you. Don't accuse him of liking her but tell him that it makes you uncomfortable because to you it seems like they're flirting. He should understand that it makes you uncomfortable because I'm sure he would be jealous if you were flirting with your ex-boyfriend in front of him.

If he denies that they're flirting then the next time it happens and you're there call him out on it, to show him how much it really bothers you.

The reason the ex girlfriend is so overly flirtacious in front of you is because she's jealous that he's your boyfriend and not hers.

Always try to remember that the person he's dating is you, and not her .
