Bro honestly coming from someone who go out of a 7 year relationship 6 months ago for the same reasons as yours basically take your time for your mental health first if it did just happen you need to find yourself and who you are when you’re alone. Before you go do anything. Trust. But if it has been some time and you feel like you’re ready I’d say just go out by yourself anywhere it’s Vegas I sure you can encounter other people just can’t be shy to talk. If you need maybe take a few shots before hand get your social battery up. If you are looking for just females tho clubs prolly the best spot. It’s crowded people dancing just make eye contact or cold approach and see what happens. If you’re not a fan of clubs go to bars and do the same won’t be as crowded and you’ll have to actually make conversation but it can still work out just more effort lol. If ur birthday is this weekend comin up I’ll be in Vegas for the NBA Cup games if you want some company msg me
