Why I can't straight RP and handle IUs'

So the whole story is.

I was in a straight rp for about 7 months.

My character dated an IU. Turns out she went crazy if I talked to anyone but her. I would be gone a lot because I was in high school doing other things besides rp and she would get so upset with me and freak out that my character was leaving her IU. She kicked me out the RP like a few months later even though I was on hiatus. Doesn't matter anymore but its so hard straight rp.

+PS this was when I started rping in kpop so real people. She wanted to all the time but I wasn't comfortable with it because I was rping a real person and I never before like that.

Sobs the relationship was cute for like a month though. :<
