Oh, I so can relate to worrying that you will never be loved or love again. Right now it seems to me that my children's father has happily adjusted into someone else's life as well. Then other times, I think that it just looks that way. We will never really know because they would never, ever really tell us otherwise unless they snapped out of LaLaLand.
I can relate also because I am petrified at the thought of becoming involved with someone. Because of my children and their well being and also for my own fear of starting over and getting adjusted to someone else and their habits and needs, etc. It just seems like too much. But then again, being alone for the next several years is too much to ask also (I am still in my thirties).
So, six in one hand and half dozen in another. The truth of the matter is these are our decisions and only we will know what the right thing to do and when to do it actually is.
So, I said all of that to say this to you. Fears are okay, they help us grow. It is okay to feel afraid and unsure. It is a natural process in this mess. When you are ready to move on, you will know it instinctively. It it almost transparent when it happens.
In the meantime, take good care of you. You are a wonderful person, this is just a bump in the road.
