The OP is too soon out of a long serious relationship. The long distance dating isn't really the problem... the problem is that he's going too fast.
I know what I am talking about, and I know how he feels. When I was divorced, I felt like I'd been let out of a cage... my emotions were all over the place. It was REALLY tempting to jump back into dating... but I rationally knew that I wasn't ready. I do not know the situation with the OP, but I needed to build back my wealth.... which took me 7 years.... my daughters were minors, and they have a bat sh1t crazy mother. I needed to worry about them. My health wasn't where it should be... during the separation I had drifted into a bad habit of drinking too much... and not getting enough exercise. I was an emotional wreak. He might not have financial issues; his ex might be a normal sane woman who he has no worries about how she is going to treat his kids.
Coming out of a LTR that involves kids, a man's priorities must be:
(1) His personal health and mental well-being.
(2) His kid's health, safety and mental well-being.
(3) His personal finances and professional development.
(4) Rebuilding his tribe of friends and family that were alienated by the relationship.
(5) Dating.
Chicks are last. If you are fine, your kids are fine, your finances are in good shape, your family and friends are connected.... then okay... start dating. For me it took 2 years... seriously TWO YEARS before I was mentally ready to start dealing with the emotional machinations of chicks.
OR you can be like my dumb@ss brother, who jumped into relationships with women before the ink dried on his divorce papers TWICE. He was already a fvcking mess... and all he did was take on MORE chaos... which did and is currently causing him no end of problems. His most recent wife he is struggling to keep her happy by buying a new house (he could not afford), and is spending like a drunken sailor on his new stepson. Meanwhile he has turned his back on his 5 kids and 10 grandchildren. He has two of his sons who are a mess that really could use his help to get them back on their feet... but he has abandoned them... because he is focused on this new wife and her kid. He tossed out our mother because she didn't want her around anymore. He is headed full speed into a telephone poll... just like the last time.
Okay... now on LDRs... these seldom work out, I could provide COUNTLESS examples of how this goes sideways. It's expensive in terms of time and money. Think of it this way... in this case, the distance is an hour away... best case that's $30 in gas and mileage on the car.... then the cost of the date... so a minimum of $100 per date. But more important, that is two hours of time that can better be spent in the gym.
I've had FWB situations with women who are dating men long distance. I don't do this anymore because it takes too much distracting emotional energy. But if you are in a LDR with a woman you just don't fvcking know what is going on with the chick you are seeing. These men have more money than brains. One, RS (her initials) is engaged now to a guy that spends a sh1t load of money on her, private planes, awesome vacations, and before they actually got engaged hooked up with me regularly. One CW, has been married for a year, this guy spent a **** pot of money moving her to Houston, a couple of months ago she came into town on business and wanted to stay with me when she was here, naturally I passed, but there are men that would have jumped on that without any thought of ramifications. I just got a call yesterday from a woman SD, who is dating a wealthy dude in Columbia, another guy spending a lot of money on her, and wanted me to come over to her place (that this guy is paying for) Saturday. Yeah like I'm stupid enough to re-start something with a chick that is dating a rich man from COLUMBIA, you know.... where most of the nation's cocaine supply comes from... but I am certain that after getting off the phone with me, she hit up the next dude in her cell phone contacts who is thinking with the wrong head that will smash that and possibly end up 'missing'.
Men can make a LDR work: women can't.... sorry that is the truth. These situations are a nightmare for men, the OP's chick is an hour away so it's not too bad, but my advice is that there are too many women that live near him to try and make something work with a chick that you have to drive a long way to connect with.
