DG, I notice two vey important things within your post.
One is the fact that you know that it's nothing you can't move past. The other is an apparent insight you have that allows you to see how your own issues may effect your partner.
Given these two things, I'm sure that whatever the problem is, the two of you can work it out and move beyond it. We always tend to take out our own issues on the people we love and care about the most. It's an awful thing but, it's just human nature. When we're able to be honest enough with ourselves to realize that we're acting unfairly and can express that to our partners, or whomever we've hurt, the issue can be resolved.
From what I see on this board, you're the type of person who is not afraid to do that and therefore will always be able to get beyond whatever issues arise. Things always work out when you can look at yourself objectively and communicate with your partner.
