Hi, first post. First of all thanks to Mumsnet community for helping me get some relationship clarity, have been following other relationship posts with great advice. I always had a gut suspicion something was wrong in my long term relationship. This community finally gave me the guts and ideas to act on my suspicions. Have just found proof of DH cheat, suspect multiple casual partners. We paying mortgage for house and have young DD- DH has been avoiding time with us both in order to have hookups. I thought our relationship was strengthening after baby craziness. Anyone whose been there, what next? And what do I tell DD when her life changes?
