excitement for looking for a new man has gone

So I'm a single mum and all my time and love is taken up by my baby Jacob, but before I even gave birth the thought of meeting a new man , getting to know him and eventually dating him just daunted on me. I couldn't be bothered. I think that the bad experience I had with my husband has put me off because regardless of me knowing him a year prior to getting married and him being all lovely and nice it soon changed and he became this abusive asshole.
