I suspect my boyfriend has been unfaithful to me ((((
I found the way to check it: http://www.rp-test.5u.com
But I don't know whether it is reliable…
What do you think about this test??
Did anybody use it?
Maybe somebody know similar method?

It seems kind of sneaky. If you need that sort of "tool", then your relationship is probably in trouble.

No never and if he was im going to kill -_-

I doubt your boyfriend will even open the e-mail that contains the test or even answer truthfully if he does. I wouldn't answer those kinds of questions if someone e-mailed that to me.

I suggest you just stick to your instincts and try to get some evidence and/or information before you jump to conclusions. Your woman's intuition should be able to tell you more than this scam of a test.

i don't think paying $14 just to see if your bf is unfaithful to you is kind of out there.
why not just trust your instinct or your bf?

Eh, I wouldn't use that. You really don't need something like that to tell you if he's been cheating. Who knows, he might not answer that truthfully, especially if he hasn't been truthful in your relationship.
If you have serious doubts about him, then I think you need to find some evidence. Maybe ask him, but then again he could always deny it.
