It is sort of difficult to say with an Aquarius. As far as getting him to express his feelings is concerned, he first needs to admit he has them. If you have known each other 5 years, and have spoken to him before about being his girlfriend, then maybe hold back a bit.
With your chart you are probably very charismatic and charming-- I'm sure there are many men who would wish to be with you. Perhaps you should pull back from him and see how you feel around other people. Maybe, if you don't already, keep a journal for him only. Write how he you feel about him. List the positive and the negative, and perhaps feelings associated with him (i,e, do you feel happiness and euphoria throughout the day in relation to him, or do you feel anxiety and confusion, things like that) . Also, any dreams you may have with him and what you think they symbolize.
This would effectively accomplish several things:
1). It would allow you to see how you feel with him in comparison to other people.
2). It would give you some space to evaluate your own feelings.
2). It would make him miss you. Aquarius tend to want what moves is far from them (because they have such a fear of being closed in). If you still want to be around him, and he wishes to be around you, this may be a good break. BUT, if he does change his mind after you are apart, don't go right back to him.
As Taurus women we tend to always be available and loyal to people, and as a result are often unappreciated. What very few people realize is how deeply Taurus actually feel things. Our polar sign is Scorpio--one of the most emotional and passionate signs in the zodiac. Taurus is often seen as Scorpio's opposite, and therefore not considered to be as emotional or passionate (dependable, unmovable, solid). This is not the case: rather, Taurus will submerge their emotions deep within (until boiling point).
Because you have double water, you are even more sensitive then a regular Taurus. It is important that if you are with a partner, they are able to accommodate your emotional needs.
Keeping a journal or interacting with others may allow for some new input in regard to your relationship.
If you like , I could try and do a tarot reading for you in regard to relationship, although I am not sure how good it would be. Just let me know
all the best,
