Sorry to hear that you’re struggling. 
I divorced my XH 7 years ago. He told me nobody else would be interested in a fat 40 year old mum of 3.
I actually had a few good dates with nice men, lots of interest and then met my DP online, who is lovely, very romantic, thoughtful, generous and sexy as fuck.
He’s taking me on an amazing holiday next month, gives me foot rubs whenever he visits, sends me lovely messages when we’re apart and buys me gifts for no reason, just because he’s thinking of me. He’s a treasure and has only got better and better since I’ve known him. Of course I’m pretty good to him too, so it works both ways!
Obviously second time around things aren’t quite so simple, we both have DCs in the mix, so having to consider them means we aren’t free to do exactly what we want all the time, but we get to spend a few nights a week together, get to go on holiday while the DCs are with their other parents and generally have all the good bits of a relationship without the drudge of living together.
I hope that one day we will be in a position to marry and move in together but in the meantime I feel like I have a good balance of alone time, family time and couple time.
No reason why you can’t find something similar or even better to fit with your circumstances.
