I've chosen not to live with anyone after my marriage ended.
I had a good relationship for 7 years, but I enjoy having my own home.
I'm in my 40's, my advice to my children's friends and younger relatives, when they seperate is to work on their self esteem and think about if they are getting all they want from life.
Relationships and life are supposed to be fun.
Most people who have had break ups haven't had a lot of fun, for quite some time.
I think you should give yourself time, to recover, whilst just having fun, flirting and enjoying being sexual again.
Question why you need "to be wanted". I think for a lot of women it is a combination of low self esteem and social conditioning, in truth most women get more fulfilment out of good friendships than their relationships.
Alongside, don't ignore red flags or compromise on what you really want, most people have just spent a long time doing that when the've not long split up.
It is a cliche, but it is the start of a new life and a relationship is only a small part of that.
When it comes to finding a good long term partner, children of any age, don't stop that. Children don't stop you developing friendships, or dating (unless you have child care issues of course).
Your friend is just going through a natural/common stage of a break up.
