I don't mean to sound critical, and you can take this with a grain of salt from sometime in their 30's, but 25 is a long time from where you are in your life. If a guy "has his life on track" at 25, he would be looking for something more serious. Are you prepared to think about the long haul in a relationship? Like needing to think about kids in 5 years? Two months is usually long enough to say whether you want to get a little more serious or not, and if you're thinking you have found someone a more in line with you now, the older relationship is not going to get any better.

It's hard to say if the new guy is better. You really don't know him yet. He might be putting on an act, he might not actually be interested in you, he might see you as sometime in a relationship, he might be telling you what you want to hear, etc. If he knows you are in a casual relationship, is he trying to pull you out of it, and what does that say about his motives? Would he do that behind your back later with sometime else?

Personally, I look at how much I enjoy the time I have with someone and how they treat my needs. If someone only has time for me when it's convenient for them, then I'm not really that available. For me, love is valuing another's needs as equal to my own. I want them to be happy as much as I want to be happy, and each person's presence helps the other. If at some point I realize that isn't going to happen, I end it. Life is to short to spend it playing games and trying to solve puzzles about someone else's motives.

I can't speak for everyone, but my experience is that good relationships feel easy. Everything falls in place at the beginning. The ones where it seemed like work were the relationships not with my time and that didn't work out. I don't know if any of this applies to your current situation, but I think you might just want a general perspective on judging people and their motives when it comes to relationships.
