My partner of 5 years has become so detached to me I feel like a lodger walking on egg shells, we have 2 kids together 3 years old and 1 years old, I googled all his symptoms and came out cocaine, we had a lovely family day out Saturday (for a change) and for some reason he said I’m going for a shower so I gave him 5 mins then crept upstairs and caught red handed snorting coke, I’m in complete shock and crying yet he turned it all around on me, we are in our 40s and he owns his own business which has always done well yet the last 6 months he’s had no money, not wanting to do anything, sleeping all day but in his office all night, we used to be so close(sex every day) yet we have had it once in 6 months, I asked him if he’s having an affair as well as he clearly don’t want me plus last month he had cold sores on his lips yet we haven’t kissed for months and he became abusive and angry, he’s denying everything saying it’s just at weekends but I hear him sniffing and blowing his nose every night, I asked him out right how long has this been going on and he said about 2 years, I feel like such a mug how did I not realise ??? I love him so much but don’t know what to do next as I don’t think he wants to change his ways
