Peanut, you are the only one who can answer that question for yourself. Your relationship is still very young, and I assume you are as well, but if in this young state, with no kids, your R is already hitting these kinds of rocks, then you are very right to question it. If you're not actually married yet, then (if it was me), I'd want to find some kind of resolution for this before moving to a deeper commitment. And certainly before involving children.
For myself, looking back from the POV of a 25-year marriage, with 3 kids, I can say definitely that for me, it is, and has been, worth it, even though there were a LOT of years when I asked myself that very question. I may still have times ahead of me when I will ask that, so I don't think it ever goes away entirely, but W and I are now in a VERY different space together than we were a few months ago, so I do think the answer (in my case) will continue to be "Yes". However, the answer to your ACTUAL question is, "Yes", I HAVE wondered at times if it is worth it...
