I’m sorry that sucks but never do this for an ex for this exact reason

That's a biiiiig yikes man. Even if she wasn't dating someone else.

You should written her a song instead. You'd save $100 and get a free restraining order. And the knowledge that your ex and her new man are having endless laughs at your horrible song, and then lots of sex.

I question what you thought was going to happen here. She's an ex. Also, you're lucky she didn't think it was creepy as all get out and escalate it.

Nothing says "i love you" like expecting her to buy uncomfortable, impractical lingerie designed solely for your viewing pleasure 🙄

If you're not dating, lingerie as a gift is a no no.

You're hilarious 🤣

It’s simple - Don’t buy gifts for an ex. You could send a card or a text on a birthday or something (even that’s not a great idea, but it’s less creepy than a gift for an ex). The short version is your ex has moved on. You need to do so too. Time and attention spent on an ex just takes away from the possibility of finding your next love interest. And lingerie for an ex is just creepy.
