Sorry if this is addressed elsewhere and I didn't find it.

Basically I was in an open relationship for a few months, so I'd still hop on Tinder once every couple weeks but I was honestly so satisfied by my partner (not to mention busy schedule) that I didn't care about any of the matches.

So now there's this girl I matched with 3 months ago, I'd like to shoot her a message. I'm not immediately on her radar anymore so I'm really not sure if I should open exactly the same as I would with someone that I was matched with, say, yesterday.

Also, I'm not sure that I'm necessarily bad at opening in general but I just never know anything unique to say in such a superficial dating app. I'm sure there's tips for this all over this sub but if you've got any then feel free to throw them down as well.
