<human>: Could you distill the essence of the text into 1-3 sentences?

We broke up a bit over half a year ago, mostly over mutual incompatibility (in my eyes), as well as, to a considerable degree, my discovered feelings of previously unprecedented deepness towards someone else.

It wasn't the nicest breakup, but it wasn't the worst. We stayed in touch for some time, and then almost stopped talking afterwards for a while.

Until recently, when she started slowly getting back at me, with more frequent texts, questions, small favours, etc. One time, out of nowhere (although, to be fair, with my somewhat manipulative quiet encouragement) she started spamming me with her nude pictures. Of incredible shamelessness, I must add (never was that way even while we were in the relationship). Because I told about this incident to my new SO (cannot call her my girlfriend, mostly only due to troublesome logistics between us, outside of our control at this moment), it directly endangered my new relationship and was generally very embarrassing.

She has also been getting me "gifts", using various excuses to stop by my place to bring me snacks that she knows I like and linger there, offering help with chores, ignoring all the polite requests for her to leave, for as long as possible.

I ended up blocking her number, but I'm fairly sure she might find a way to contact me some other way. I don't quite know how to deal with her, because I do feel guilty about leaving her like this (our breakup was long overdue and she got way too attached, while in turn I never developed any meaningful feelings.)

I can't pull out the "I'm with someone else now, deal with it" card, because, again, that other girl is not currently in this country, and we are engaging in a long-distance thing, which is a whole other story.
<bot>: Dealing with an overly attached ex. Got a new quasi-relationship that I want to focus on, but the guilt and constant active reminders of the ex get in the way.
