Feeling lonely

My boyfriend moved out because his smoking was affecting my asthma. So now I live alone and I get lonely. I've only ever lived alone a couple of times for short periods because i've always been in a relationship. I have hobbies I can do so things to pass the time. But I haven't got any friends just him and family. It's the silence that drives me insane. I've got no-one to talk to. He is in sheltered accomodation and so has the other residents to talk to in the communal garden and sitting room. He has more of a life than I do. I feel annoyed because he chose smoking over me. He gets to have fun whilst I am just left here alone. It just doesn't seem fair because i've done so much for him. I looked after him whilst he was sick and everything. I just needed to come here and vent 😩
