you need to provide some background to the question. Why is she worried about this? Have they been having an on and off relationship?
The chart shows Mercury (the guy) in detriment and Moon also in detriment, so something in this relationship does not move smoothly. Mercury does love Jupiter but its in detriment, he is not very action oriented and Jupiter is more strong, being in its own term and being in 5th, Jupiter (the girl) wants romance and love and happily everafter but with this heavy Moon influences things are not very romantic, or at least things are not moving toward marriage right now. There is no aspect between Mercuy and Jupiter. However, Moon will translate light between them, but Moon will also translate the light of the square from Sun and square of Saturn to that poor Mercury. That is too much for Mercury to handle at this time.
His secondary ruler Sun is exalted, so I think his focus is on other things right now. Sun rules his intercepted 2nd house and located in turned 10th - I think he is more focused on career and finances to think about marriage right now. But he does care for the querent. The intercepted 2nd and 8th show the real issue, they need to focus on finances first... before they can make that kind of committment, as ruler Sun and Saturn the opposing each other...
Marriage is not out of question sometime in the future, the chart shows a lot of issues right now for marriage to be a priority. Moon is way to weak to make things happen right now. So its a no for marriage for the way things are...
