You are Saturn in your second whole sign house, which makes me think that your self-esteem may be affected by your relationship with this man. That’s completely understandable in a situation where you may want something more committed but you’re in something that’s undefined. Another interpretation could be an interest in financial security through having a committed relationship with the quesited. Not saying that’s how you feel, but it’s what I think when I see your significator in the second for a question like this.
He is the Sun in his second whole sign house, or your eighth. This makes me think you might feel some grief or sorrow about him, and/or that he’s focusing on his finances and material wealth and that focus is a factor within the context of your question. He also has Venus in Leo in his house, and Venus rules his turned 3rd and 10th, so that could be describing his situation or another person that factors into your relationship with him. Venus could even be you if you’re a woman and you tend to see Venus as an additional significator for yourself when you ask these types of questions. But, you as Saturn also can’t “see” Venus by aspect, so Venus could represent something about him or his life that you’re unaware of.
The moon is well dignified, but it is sitting in the sixth house so it’s not in the best position. Moon in the sixth makes me wonder if you’re feeling love sick or getting that sick to the stomach feeling that something isn’t right in your relationship with him.
I’m not confident saying whether he’s using you or not from the chart, but his significator is in Mercury’s sign, Venus’ triplicity, Jupiter’s term and Mercury’s face. So not in any of your dignities within the context of this question, which suggests he has other interests or focus areas represented by these planets, their house placements and the houses they rule that are top of mind for him right now. That said, Sun and Saturn are mutually applying by opposition without reception, which is a difficult aspect as it can symbolize delays, trouble, disagreements, eventual separation, etc. Mercury, the ruler of your fifth and eighth whole sign houses, is also applying to Saturn by opposition and meets Saturn first.
Mercury could be translating the light of the Sun to Saturn as it separates from the Sun and next applies to Saturn, but it is a combust Mercury in the whole sign eighth house, so I’m not sure how effectively that Mercury would be able to translate the Sun’s light. Like I said, I’m still learning so if this is not translation of light I hope someone with more experience can chime in and explain. The Moon also aspects Mercury before Mercury opposes Saturn, so even if Mercury is translating the Sun’s light to Saturn, I’m not sure if the Moon here is prohibiting the translation of light.
I hope you’ll update this post on what happens! It can help us all learn better.
