To wonder who brought the STD into the relationship?

[MeconiumHappens]

I'm puzzling and could do with someone in the know's opinion on this.

My friend is in a long term (12 years) relationship. The past year has been rocky for one reason and another, culminating in her 'playing away' for a couple of months about 3 months ago. She assures me she used condoms, but i guess you never know. Her partner found out and it all came to a stop.
Shortly afterwards her partner developed some symptoms, was tested and positive for an std, she doesnt know which one. She then went to the clinic for treatment and when she was screened she came back clear. She was treated preventatively with an injection in her bum and antibiotics, if that throws any light on what it was.

Her partner lays the blame squarely at her door that she caught this from the other man and passed it to him. However, if she didnt have the std, could she have passed it to him without contracting it herself? Or is it possible he had a 'revenge' shag elsewhere and caught it?

Sorry for introducing std's over breakfast ;)

She could be a carrier. That is a possibility. Some STDs lie dormant for a long time then wham there you go, i.e sometimes male symptoms take longer to appear so he could have had it for ages, saying that however surely she would then have caught it from him?

Don't know anything about STIs really to be honest.

However is it standard practice to give antibiotics and jabs to people who are clear just in case? I don't know why but that shocks me!

Sounds like a shit relationship they are in though!

What symptoms did he allegedly develop? Did she go with him to the clinic? Has she seen proof positive that he had a std and was treated? Did she see any prescription in his name?

If not, he's most probably playing mind games by way of revenge for her cheating.

Yeah, both the above are odd. I would want to know exactly what i was being treated for and exactly who had given it to who. And it is weird they treated her if she was negative, but maybe thats standard issue if youve got a partner infected, just a matter of time before she developed something?Dunno abut symptoms, something to do with the end of his penis, but i didnt enquire into too much detail. It was about half an hour before tea time . I cant think he's using it as a stick to beat her with (ha excuse the accidental inuendo) if its not true because the clinic wouldnt have treated her if she was negative and had no recent contacts surely?

when she told me i said that surely she couldnt have given it to him if she was negative, so its not like i havent said anything. Im guessing that, as fluffy said, its the difference between wanting to know or not. Another can of worms to start opening at an already shitty time.

fabby the STIs that are dormant such as herpes and warts don't require treatment with abs or injections they're chlamydia and gonorrhea, to be fair to him it is ever so slightly possible that the body can eventually clear chlamydia on its own if she had it a long time but doubtful with gonnorhea.

The problem with STIs is that they are really difficult to pinpoint the cause/original donor so to speak. In a relationship what i would probably do is forget all about them and look at it like this, is it working? Is it not? Why are people cheating, will they ever get over infidelity? Is there trust, these are what answers questions not who gave who what because it's never clear cut.
