I'd take your friend to be 11th. It appears there is no romantic involvement between you and you've been friends with him for 8 years, so 11th it is.
He is Sun, exalted and angular, conjunct Uranus. A planet exalted has an exaggerated sense of self, perhaps arrogant and as Lilly puts it 'assuming more unto him then his due'. With conjunction to Uranus and recent application to another exalted planet Jupiter, who like Sun has the same sense of superiority, I think your friend just wants to break free for now and perhaps associate with people who offer him the same things he is looking for. Uranus is not used in traditional horary, but I pay attention to it when its conjunct a significator and it is clear Uranus has an influence on your friend. Uranus brings disruptions and need for sudden change.
Your ruler Venus and his Sun, both are in mutual negative reception. Sun has no time for Venus, being in her detriment. In the past, Sun exalted Venus, being in pisces, but a change happened. Sun will oppose Mars next who is placed in fall of Sun, he will go through some more changes, arguments and separations which will hopefully get him to realise what is important.
For your part, Venus has just completed the difficult aspect to debilitated Mars and Saturn and soon enough it will enter its own exaltation. I think give this time. With early ASC you have not see the end of this relationship yet, more is to develop. With Venus in fixed sign, it may be months before there is any resolution to this.
best wishes!
