Some want to say that just virgins abstain from sex and do not have sex at the expected customary time; however, one does not have to be a virgin to play safe or to their standards or choices!!! If she has no intention of making your relationship sexual, then you should accommodate her wishes.
That means nothing more than a brotherly hug and a kiss on the cheek from now on.
Hopefully you will all have fun meeting singles and try out this online dating thing... So we have to look at other causes..guess is she is still having issues because of her last relationship.

Therefore, if you had any sex protected or unprotected, as there is not 100% protection besides abstinence, within the past 6 months, you might infect the one you say care so much about.
Moreover, people who really care so much about each other, should obstinate from sex for 6 months and get tested to make sure that they do not infect each other.
When some things bothers me or I'm not sure about a detail especially of that nature , I always want to get to the bottom of things and I leave no stones unturned. Nonthreatening, but very honest, direct conversation asking her what she sees. Then when everyone has lain their cards on the table, you make a decision based on what you know, not what you might infer from half statements she made about a bad relationship.
BTW, the relationship, such as it is, is sexual, she's made it sexual, she's just not having any part of getting him off or having intercourse.I do not want someone to be with me because of sex.Moreover, six months is the average time for many STDs from the time of contraction to show on test result.By all means, continue to be friends with her and spending time with her if you enjoy her company.But cut off the kissing and other extracurricular activities, since its doing nothing but leaving you frustrated and confused.
