OP, there are nice bits to being a single parent - there are pros and cons to many situations.
I was a single parent for a few years. I didn't have to compromise, no one challenged my parenting style/decisions, I was the master of all I surveyed - I decided our menu, where we went for the day, what we watched on TV, what my son wore. My son didn't have to compete for my attention or my affection.
I did go to university whilst I was a single parent and the lack of distraction and the fact DS was a good sleeper meant I got a first. I was well respected by the lecturers and other students for the fact I didn't use my LP status as an 'extenuating circumstance'.
But I was lonely. Night after night I spent the evening in the living room, on my own, sewing, working, reading, glass painting, playing my instruments... But every night I did it on my own. I was in an unknown area, and in the early days I knew no one, I had no friends, no family support.
Everything I did, I did on my own. When my son spent a week in hospital - I did it on my own. I didn't have a break. The nurses told me other parents were complaining that I wasn't stopping my son from crying and disturbing their children when I needed to get 40 winks in the parents waiting room.
Every funny TV programme I watched/funny incident I witnessed/every AIBU moment/every idea or plan I had, I did it on my own. I had no one to share it with. When I was ill, no one took over looking after DS. No one said "God you look knackered, do you want a cup of tea?"
There was no one to plan the future with, no one to get excited with, no one to share my worries and fears with. I faced every day alone.
No one to tell me it was going to be ok.
No one to tell me to get a grip.
No one who gave a shit about me or DS.
No one.
So yes, by all means, enjoy your alone time with your child, but don't every think that whilst you are doing so you have any idea what it is like to face life completely alone.
And be careful what you wish for.
