I met my bf just over a year ago. Things moved fast but at 39 and 44 we both wanted to settle down. We were on the verge of putting an offer in on a house and had talked about getting engaged. We’ve had a lot of family stresses to deal with in our first year. My grandfather passed away and his mum has severe dementia. She has declined rapidly and frighteningly but remains living at home. I have always been extremely understanding and supportive of this situation.
A month ago he suddenly decided out of the blue over the course of a weekend that we should split. He said he needed to focus on caring for his mother and working. It was as though he had flicked a switch and overnight he turned into a different person. He became completely cold and distant not only with me but his entire family. He has stopped communicating with his brother and two sisters. When he does speak to them he is rude and abrasive. He refuses to discuss me, even when they have tried to ask him. His family are all completely baffled as to why he has done this, particularly as he had told them I was the one and suggested he was planning a proposal. He is being utterly vile to all of them. I have had minimal contact with him since we split and it is like speaking to a different person. He was extremely loving and affectionate but has become monosyllabic and withdrawn.
I am so scared he is having some sort of mental breakdown and will do something stupid. His family are so sick of his rude and mean behaviour they are washing their hands of him. I don’t feel like I can even reach him anymore and it worries me that no one is checking in on him. I’m at a loss of what to do. I still love and care for him. Does this sound like some sort of male depression/breakdown/crisis?
