Hi, I’ve been a single mum for 10 yrs now and have just started to feel like you are feeling. I didn’t do anything about it before because I wanted to do it my way, we were a team and it was ok to just be us, mine were 2 & 6yrs when I started out as a single mum. It will get easier when your toddler turns 4 yrs they will have a big personality you’ll have a relationship where you can relate in different ways than before and its gets more interesting, they become little people:)
I had a brief relationship in the middle, he had 3 boys and was very militant with his kids and had very different views on how to raise children and it wasn’t suited to our family so I decided its not always the best thing to have someone else but now mine are 12 & 16 yrs and don’t need me in the same way anymore its become very lonely.
Just remember to slow down sometimes and just watch and observe/ treasure the moments, I didn’t slow down until my youngest was 8yrs and feel I missed so much just going through the motions and trying too hard to get things done.
It does get easier as they get older and there are so many amazing changes and challenges along the way.
