I remember my now husband telling me that he didn't know if he still loved me or our children. He said that nothing had changed, so he thought he probably did, but couldn't be sure. It broke my heart, but I told him that it was all going to be OK because I loved him and them enough for both of us.
For us things have worked out and we're still together - it's not been easy and it doesn't work out for so many, but for us it did. We've always been open and honest to each other about how we feel etc.
