My opinion is that family doesn't always have to be blood, or connected by marriage, it could be anyone who feels like family, as long as the feeling is mutual. It is my opinion that, as long as there is a mutual sense of belonging the relationship could be considered family - provided all parties involved are in agreement. Thus family can include close friends as well and life-partners.

Am I wrong?

I ask because somebody argued that people leave me because I eventually consider them family, which he argued is an abnormal thing to do.
