How old is DD?
Are you just not in the headspace to date?
When DD was little I decided not to date after seeing a really lovely man.
Financially it took a toll - going out, new clothes, - money I could have been spending on doing things with DD.
Cost me in time - time I could have been with DD, or doing chores so I could spend quality time with her, or me time so I could recharge.
Emotionally it cost more than I had to give, when you are the one making all the decisions at home and have someone relying on you 100% I just didn't / couldn't be there to provide the emotional support of even interest required in a relationship,
Being all touched out - having a toddler/ preschooler at the time I didn't feel particularly sexy and the last thing I really wanted was more touching or at least the amount normal in a new adult relationship.
The knock on effect of this means that actually, having DD at 23 means I never really developed those relationship skills so if I do choose to date I'm starting from the beginning. The last man I dated was still in that post teen / early 20s gangly phase and now many men my age, are hairy, grey haired, wrinkled, beer bellied, likely to be married and divorced and are 'proper' grown up men which is quite the difference to before. I've obviously aged too but you forget that when it's yourself and certainly don't look like pre 30s me now.
But I don't regret it, I focused on me, spent that money and time on investing in myself in driving lessons, OU degree and financially getting myself and DD into a good place. She is grown now in her mid teens and she'll be my only child and I can look back on my parenting experience knowing I was all in and really present for it all. What dating holds in the future for me I have no idea but I'm certainly not well equipped for it and feel a big like a teenager.
So it depends on what you want, before make any rash decisions really think about it. If you want to be in a relationship then sacking off a perfectly nice man is daft. If you actually just need to be alone right now that's fine too but consider the pitfalls too.
