So sad today

Back in Oct I got my pap smear and I never gotten my results so today my doc called me and told me everything from the pap was good but I got trichomoniasis and she asked have I been with more than one person I said no me and my boyfriend been trying to conceive later on he told me a few years back he got oral sex from a girl from a party I'm so hurt and I been doing everything I can to have a baby with him and he does this to me
