<human>: Can you provide a brief overview of the text?

To start out, we have a had a great relationship (I know she's the one). We've talked about marriage seriously and about moving in together for a long time now. The time is just about there to start the process (2 months away). We felt perfect the last few weeks and I know she can't hide when she's feeling off about anything. We've had short periods where we don't "click" quite as well as usual, but it always gets fixed a few days later. However, now that we are about to move in together she tells me this morning that she's been feeling weird about us lately. She says she's worried because she doesn't feel like we've been "clicking" lately and she feels like we don't have the same spark as we did when we first starting dating and she "doesn't know what [she] wants". Now personally I understand this, but from experience and what I've heard, it's a pretty normal occurrence to "lose the spark" if you're comparing it to initially dating. I have also had these feelings, but they've only lasted for a week at most on and off. I think this is because one, we have been in a serious relationship for two years. Two, we have both been very busy with work and school and have only been seeing each other once to twice a week. Three, she has a lot planned ahead for the future and four, she comes from a military family and is not used to having ANYONE being in her life for more than 2 years at a time. The biggest thing is that she says things like this (almost verbatim) every other time she starts PMSing and it's starting to take a toll on me. I think it is the birth control she is on because others that I have talked to have had similar experience with their SO's. I think that moving in together will cause the "spark" to come back because our relationship has been admittedly pretty stagnant for the last few months. Also, yesterday she helped me set up a tour for an apartment complex we were looking into. Today this ensued. Any opinions/similar experiences?
<bot>: My girlfriend is having commitment issues 2 months before we have been planning to move in together. I believe her normal feelings are being amplified by her birth control.
