I've been with my boyfriend for six months. Its going well. We have issues with the ex who left him 14 months ago (mother of his dd being nasty and demanding and texting him a lot) but we pretty much get on with that in our own way. The past month or so I've had this feeling in my stomach that something isn't right. I don't know what it is but I can't shake it off. I feel threatened by his ex and I've never been unconfident like this before. He doesn't keep our relationship a secret or anything so I should have nothing to worry about but this feeling of uncertainty is driving me mad!
