<human>: Can you give me a shortened version of the text?

i am in a relationship that i am overall fairly happy with. as with any, there are several sticking points. one that i find myself thinking about a lot is this. over the past four years my SO has asked her doctor for an AIDS test, twice. she is my second sexual partner, i was my first sexual partner's first, and i am her second as well.

the first test i was confused but okay with, because sure, from her perspective maybe i wasn't honest about my past relationships, and in general it's a pretty good thing to know about. the second test, i sort of feel like the only way that makes sense at all is if either she cheated on me or suspects that i cheated on her. i asked her about it and she said that she's a hypochondriac, but i had a hard time accepting her reasons for getting it.

i feel shitty for essentially being upset with her for having good sexual health habits, but i really don't see why she would be worried about it unless she either thought that i was cheating on her, or cheated on me.
<bot>: am i being unreasonable for assuming that my partner getting tested for AIDS twice in our relationship means that she thinks or knows one of us has cheated?
