I’ve never seen anyone (that I know personally) that has ever survived a long distance relationship. The distance thing is a real problem for several reasons. Spontaneity is non-existent. Every meeting has to be planned. You won’t be able to see this fellow every day, which I assume would become important to you if you get any more serious with him.
What if you needed him or he needed you in an emergency situation? You’re 2 hours away.
And the biggest problem with a LDR is that you never really get to know the person in a real way. It’s just a make believe life. You only get to see him when he’s alone and on his best behavior, most likely when you guys are having an amorous time together. Not with the kids around, or having to withness his job stress or his embarrassing throat clearing or his ridiculous donkey-braying laugh when he’s watching his favorite TV show (that you may hate) or his hour long stints on the pot in the morning, or his messy housekeeping skills, or his jelly-smeared counters.
You also won’t be seeing him interact with his friends and family, to see what kind of a person he really is when he’s not smooching with you. The way he treats the other special people in his life is really telling, but you won’t be able to see any of that.
It should trouble you that he says his kids aren’t a problem (or your words: don’t matter) at this point. His kids should be his number one concern, but it doesn’t sound like they are. And if he is caring for them like he should, then you will always be number 2, or even 3 or 4 depending upon what type of work he does and how much time he has to interact with his ex-wife or other family members.
It’s sounds sweet for him to tell you how much you matter to him, but a sweet comment is not reality. Why would you consciously put yourself into a situation when you know that you will at best be number 2 in his life?
One of my friends, who was in her mid twenties at the time, got involved with a fellow who had a 2 year old son. She thought it would be wonderful to get together with this man, who expressed generous amounts of love and passion for her, but guess what? He had 50/50 custody of his son with his ex-wife. The ex wife was not thrilled at all to know that some other woman was spending the night while her child was there and she made a big (reasonable in my opinion) stink about it. The little boy should have been the primary concern for everyone invovled, but he wasn’t. They had a fast and furious whirlwind romance. Unfortunately what happened in their case is that my friend grew resentful towards her boyfriend, because he often had to go and pick up his son, even when it wasn’t his regular day. My friend started interacting with the child, making the child grow an attachment towards her. She wanted to spend more time with her boyfriend, which just wasn’t possible, and she also had to endure the anger of the ex-wife, who didn’t think it was proper that he was spending so much time with my friend, instead of their son. Ultimately they broke up. Can you imagine how awful that must have been for the little boy? And this was a couple that lived in the same town. They didn’t even have the added negative of living far apart.
I also agree with some of the other’s advice, that if one of you doesn’t plan to move to the other person’s city, this LDR thing is going to become grueling and very inconvenient very soon.
