Guilty

Hi I'm looking for some advice I have been with my partner over 11 years feel so guilty that he is having to go through this.I had breast cancer in 2019 was meant to be cancer free but just over a year ago diagnosed with stage 4 metastatic breast bone lung and lymph node palliative care.Before this happened I was a dedicated carer and 12 hour shifts full time 5 days a week a bombshell hit us.Now I feel jealousy has eaten away at me always said to my partner don't stay out of sympathy.But I feel so guilty as all I want to do is hide away unfair to him.My partner has no support or no one to talk to is there any men's groups where he can talk if wives or girlfriends have cancer etc.Scared he's bottling it all up
