DH's behaviour has become increasingly erratic over the past few months. At times he is quite manic, but more often than not he appears very depressed. We have had another weekend of him mainly in bed or sat on the sofa on his phone. He has barely conversed with me all weekend, and when he has he has been snappy, complaining about something really minor or making some unkind comment about me. I have tried to talk to him about what is wrong but he won't talk to me and won't access any help, saying he will sort it himself. Other than the stress of the pandemic/lockdown there isn't anything difficult going on in out lives. We are fortunate that we both have jobs, supportive families, a comfortable home and no money worries. We have 2 primary school age children. The situation is becoming increasingly miserable for us all, and I worry about how it is affecting dc. I wondering if he could be Bipolar. I really don't know how to approach this with him, and would welcome any advice, especially from anyone who has a partner with Bipolar. Thanks.
