You should be able to have a free initial session with a solicitor. Meanwhile make sure you know all about the joint finances. I was divorced when I was 46, after 25 years of marriage and was very happy in my own little house. If I felt a bit lonely, say on a Sunday, I would just go to a yoga class and then have a swim.
By accident I met my second husband quite quickly (probably because the last thing I wanted was another man) and we have been together for about 28 years now, married for over 25 and are very happy together. Good luck.
