<human>: my girlfriend and I are 23, we started dating a little over a year ago. very soon after we decided it was love I got diagnosed with a life changing illness and she insisted on sticking around. i love her and am emotionally indebted to her for the time she has spent with me as i've gone through treatments.

but over the past year there have been issues with trust. i've caught and confronted her about lying on multiple occasions. after we talk about it the motive always seems to settle on being because she wants to 'avoid conflict so as to not upset me'. obviously this has shaken the foundation of trust in our relationship.

recently there has been other stuff. 3 months ago I could hardly keep up with her sexual appetite, whereas for the last 2+ months she's been on a cycle of recurrent yeast infections and periods. to the point that we've had sex thrice in this time. we have been talking about stopping condom use and after a particularly deciding conversation about it, she immediately went to get an STD test - even though she got one about a month after we started dating.

I don't want to end this relationship over speculation, especially when she insists that she is not the type to cheat and I'm in a place where I could really use the emotional support. my concern is more with the underlying strained trust and the fact that these related issues seem to be popping up with greater and greater frequency. and if something does happen later along the road, I'm not sure I'd be able to handle it.
