The only problem is before I moved in he used to live with his ex, they broke up October last year and she's still very clingy of him and tells him on a daily basis she wants him back - they broke up because she cheated.
I don't get involved in any of this, I rather not cause more drama than necessary but me and him talked and... (this is his suggestion) he said he's going to tell her they can't be friends and that he doesn't want her in his life anymore. I suggested telling her to her face rather than text.
So he sat her down and told her basically what we discussed and this is when she says "I'm pregnant"... of course he demanded her to take a pregnancy test. I asked him the last time they had sex and he said the week before they broke up, but apparently she's saying she's not far along enough for a scan so we believe she's lying.
How do we go about this? We want to make our relationship known without having her getting involved.
