On the off chance that this really is dad (and remember, we have had it happen quite often in the past where both parties end up on this board) I am going to point out some of the downsides to moving that far away from the kids.
1. You are going to end up responsible for all or almost all of the transportation because you created the distance.Not neccesarily, always the case, and well its not that big a deal in todays world.....
2. After a while that 1 1/2 hour round trip is going to get really old....it will get even older if you have to transport the kids to school in the morning.as stated LOTS o fpeople drive that distance to work every day. and honestly I drive 5 hours one freakin way every moth for my steps, it aint no big thing when it comes to your kids
3. It won't be as easy for you to participate in school events.really? if its big enough, I bet the drive won't be that big a deal
4. As the kids get older they may get resistant to visitation because they won't be able to participate in social events and activities while on your time (unless you are willing to make lots of 1 1/2 hour rounds trips)again MAJOR projection
5. Lets say that you have 8 exchanges a month, and maybe go to 3 social events, school activities or other activities. That is 11 exchanges of 90 miles round trip. That's 990 miles a month extra on your car. With gas at 3.00 a gallon, if your car gets 25 miles to the gallon, that's another 120.00 a month in gas on top of the wear and tear to your car. The IRS says that it costs 44 cents a mile to run a car, therefore in overall expense that's an extra 435.60 a month.that IF he ends up doing all the driving, and again it may not be a big deal to him, In my house its called "fact of life"
6. Odds are that phone calls will be long distance, which adds more expense.most of america has cell phones now-look into it
So, there are downsides to moving 45 miles away. However, if you could get your girlfriend/fiance to meet you half way, and you all move someplace closer....in the long run you might be happier.what if fiance has an awesome house? it might not be worth it!
