Take her toxic ex stories as a guideline for how to do her even worse.

Be the guy her mother warned her about

Knock that shit off bro. If that guy was so great, she would be with him. She's with you now isn't she?

Listen to what she says: if these something that she likes about him you can learn from that and if it's something negative, you can learn not to make the same mistake.

If she's talking too much about it, change the subject.

Well yeah this happened to me quite a bit with my ex.

I only came to terms with it (still in progress a bit) because the guys always have some bullshit to offer that you think they don’t, unless it truly is some situation where somehow you’re in the twilight zone and she prefers a garden gnome over you.

I asked my ex a shit ton of questions, to the point where she knows I’m insecure as fuck, and it turns out that both her exes did more for her than I did.

No matter what it won’t feel good thinking about her exes. My ex tried to make me jealous by describing her ex as some giga chad when in reality she seems to have exaggerated. And her other ex was ugly as fuck, and this made me insecure too. So with fake giga chad I was like “I’ll never measure up”, and with garden gnome I was like “am I ugly??? I must be ugly if she fucked this guy and liked him”.

So in conclusion, I’m going to see a therapist because yeah tbh I can’t handle this shit either haha

I think its insecurities so big that they each even in the past. These things may or may not be true. I NEVER ask too much about her past. There is nothing good to discover.

"In most cases I am better in every way" Something is wrong here. Either you are building yourself up too high or you are dipping too low in SMV value. Odds are he was roughly as good as you just in different ways, unless you are playing a league or two below your ability.

I would examine this carefully. There will be some illumination in it either way and that may lead to peace.

She's not yours; it's just your turn.

Enjoy your turn while it lasts, and don't worry about whoever had a turn before you.

The basic issue is that you're unsure about what you're giving (eg exclusivity) vs what you're getting (eg devotion).

This is fundamentally a problem with men: the more you give, the more certain you need to be about what you're getting, and you are never quite certain she's the girl she says she is.

Solutions usually revolve around understanding what you're giving (ideally as little as possible) and what you're getting from her and ideally from other girls too.
