The chart has Taurus rising which indicates that you are signified by Venus, in the fifth House of Romance, so your mind is truly on this match. Venus is in Leo, where it is Peregrine but in the Terms and Face of Mars - his significator. You're not sure of your way here, how to get what you want. But you are definitely interested in him.
He is signified by Mars, which is in the Seventh House and in Scorpio. He's on his own territory and very much in command. So his attitude is going to be the key here to long term success. As Mars is the Water triplicity ruler by night, as well, he's full of self confidence. The only dignity of Venus that Mars occupies is that of Face - the weakest of them all. And Mars is in the Detriment of Venus. His feelings seem to be mixed in regard to you.
Venus and Mars are in a separating square, so in the recent past the relationship has been more 'off' than 'on' and I suspect he's not communicating in a positive way at the moment. The separation suggests the end of the relationship rather than the start of a firmer one. However there may be other factors here.
The next thing to check for is Translation of Light - usually through the Moon. Now the Moon is indeed separating from an aspect to Mars but it is a quincunx from Aries to Scorpio and in traditional terms, that is a inconjunct relationship. As the Moon's next major aspect is to Venus, it would have been nice to have that Moon Mars separating aspect as a major one, suggesting that a third party will bring you together.
The Moon is often taken as the co-significator for the querent, but I have seen authors use it as a general co-significator, that can 'effect' the necessary conditions. If that were so, I could draw the conclusion that this coming aspect suggests a happy conclusion. However not all authors use the Moon in this way and I don't usually either. The Moon signifies your emotions, so at the moment you appear to be 'recovering' from an emotional clash with him, or at least he is indirectly affecting your emotions. Given the inconjunct contact with Mars, that's more likely to be through ignoring them, rather than directly upsetting them.
Given that his feelings are ambivalent, you should perhaps question his motives here. As his top priority is him, is he only interested in you because you make him feel better about himself. I think that area really needs to be cleared up before you start making any commitments.
As both planets lie on the same side of the solstice line, there's no contact by antiscia so again no likelyhiood that that will bring a positive outcome.
In questions of this type of relationship it's possible to use additional significators, Venus for the female (already in play) and the Sun for the male. Whilst Venus and the Sun are in sextile by sign, the sepaation is far too wide and in the wrong direction. So I don't see these indicating a positive outcome.
So at the moment, the chart doesn't show that a committed relationship is likely, The strong feelings are more on your side than his, he's more ambivalent. Mars being in a fixed sign I don't see his attitude easily changing either. I think he's happy with the situation, but you are not. You know what you would like here, the question is 'Does he want the same thing' and at the moment I don't think he does.
Aw that's very disappointing.
Nearly everything you said is correct, apart from I make him feel good about himself. You see, I'm not sure if I do/did. He said a lot of the time I didn't because he never knew where he stood with me. This was said in the last conversation we had. He said me being off and on constantly really took it's toll on him.
Also, I really don't think he's happy at all with the situation he's in now.
When you say he's in demand what do you mean?
Many, many thanks for the reading.
