Sex with her is free, but the emotional baggage she brings last a lifetime, it’ll cost you pain, try ghosting her and you’ll discover the latter. OP will attempt to end it, she’ll say “you can’t end it, I won’t let you.” Every time the phone at your home rings you’ll wonder in fear it might be her, ain’t no future in it.

If you know which way she leans politically, then praise the idiots on the other side.
Trump, Trump, Trump, Trump Trump. or Biden, Biden, Biden, Biden, Biden

Less and less foreplay.
Less and less time, think two pump hump.
How about notifying her that you have an STD?
Nervous breakdown on your part.
Say you were laid off and are now jobless.
Let her start finding out about your drug and alcohol addictions.
Remember when you used to plan on a nice refreshing shower before seeing her? Start planning on skipping a day.
