Chouchou, the chart has a very early Ascendant so we will need more information on this or there will be more information coming so that your friend will know a bit more. Even so, we can have a look at the chart.
Your friend is signified by the Sun in the 8th house, where she is obviously worrying about this. She must have gone through recent difficulties with her husband because Sun left the oppostion to Saturn retro (his ruler). The quarrel could have been about finances (maybe he thinks she is spending too much), or psychologically seen, maybe about the fact that she thinks that he does not support her emotionally. After all, she is in his 2nd house of support. Sun also rules her 2nd house of money and the oppostion falls in the money axis.
Your friend is co-signified by the Moon in Sagittarius in her 5th, which shows that she is emotionally busy with this romantic, lover thing. She probably has confronted him with it as well, because Moon is leaving the square to Saturn and is going to make a square to the Sun who is also the natural signifyer of "men" in traditional astrology. Mars is the other traditional indicator of her husband and Mars is in Gemini (and Gemini's do tend to be flirts).
He could be torn between two things and he clearly does not know what to do (Mars is Void and about to move into Cancer, his sign of fall.) Nevertheless, he will sextile POF in his 4th house, so whatever is bothering him, probably will end well.
I think he is bothered by something because his thoughts, ruled by Jupiter (his 3rd house ruler) are in his 12th of self-undoing, sorrow and secrecy.
Jupiter has the same ruler as her husband, Saturn retro ,and retro could mean that he is holding back something. Saturn is also in his 8th house of sex, but it can also be that he is very worried about something or someone in his work. This is seen by the square he made with the Moon (a female) in his 11th house of hope. Moon rules his 6th of work. So maybe a woman in his work has made a big mistake or something and he had an argument with her and therefore had to be in contact with her more than usual, but of course he could have had an affair with her and had a quarrel with her so he is worried about that. Mars also co-rules his 10th house by the way! It is very possible that things in his career are (or meanwhile have) changed. This question was asked a while a ago and Mars is now in Cancer already.
Now when I look at his 5th house of romance, then I do see the ruler Mercury in his first house AND I see that Venus just left the conjunction with Mercury , Venus being the ruler of his 10th house, his work. So some connection with romance and work has been there I think, because both are in his 1st house.
The Moon shows us how things are developing, so first Moon will square Sun which shows some sort of male-female = relationship problem, then Moon will sextile Mercury, ruler of his 5th (oops!), than Venus (so there could be a possibility (not a certainty) of something romantic, then Moon will square Uranus, ruler (modern) of his 7th, but because I do not use modern planets as rulers, I will only look at it as an indication of an unexpected thing that will happen, to do with finances most probably, and as last aspect before leaving her sign, Moon will oppose Mars (co-ruler of your 4th and ruler of his 4th) another quarel probably . When Moon enters Capricorn he will immediately conjunct Pluto which shows that a big emotional upheaval could be the result but soon after that to be followed by a trine to her Ascendant.
