you have to think about several things.. very hard... if knowing that she had sex with someone else is gonna be a problem, dump her.. if you think she'll ever leave you again, dump her... if you think you have an STD, both of you should go get checked... there are many reasons why she wanted this "break"... probably to see what sex was like with other people.. probably to see if you were the right guy... i think most, if not all, girls suffer from "grass is greener" syndrome... they're always wondering what else is out there.. now that your'e back together, you have to decide if you're greener than everyone else...
remember, that even if you didn't do anything during the three months, she did.. and you two were apart, so she can do what she wants... if that bothers you, then just end it now because it's goign to slowly eat away at you... but if you can get over it, then you can still have a very strong and great relationship.. you just have to let it go... it's not easy, but that's what you have to do... if you truely believe that she came back to you becuase you're better than everyone else, you should take that as a compliment... it's hard.. i know, i went through almost an identical situation.. but it's doable, and your relationship, should you want it to be, will be stronger than ever...
