Actually he does like you:
You = Venus / Moon
Him = Mars
The fact that Mars is in Taurus is clear evidence he does like you, and miss you.
In this chart mercury here is the ruler of the part of marriage (162 degree Virgo). Thus Venus in gemini, represent your thinking of the relationship.
Now, while mars is in the 7th, it is close enough to the cusp of the 8th, making him weak.
The truth is that, the Moon (as your co-signifier) approaching the conjunction with Mars does imply you'll be with him.
You ask if you should fight for him....Well....
He won't be the one trying to get back with you (mars in 8th house, weak). However, venus is also in the 8th house (also weak). So it must be you the one to approach him.
Notice this: Mars in Taurus, is exalting the Moon, your feelings.
It could be possible that the reason he doesn't, or feels he can't be open is because of respect to your feelings: he thinks he hurt you in the past. Mars can only exalt the moon by being in its own detriment. Meaning that he can only respect your feelings, by feeling guilty and sad about it.
So yeah, the chances of getting back together are indeed realistic, but it must come from you, given that he is unable to express what he feels, out of concern for having hurt you in the past.
Mars is in Oriental position, not a "manly" position for Mars, so he won't be very direct about the issue.
So be honest, talk to him, tell him you miss him and want him back. He might refuse you at first saying he feels guilty about having hurt you, and that he is sorry for all that. But you guys will be together.
Notice mercury (the relationship), is in Taurus. Being in Taurus means it is under your control (you decide, since Venus represents you).
Tell him how you feel. He does like you.
