It depends on the stages you are at.
In the begginingm it usually means that they klike u but they r very one track so if the tuarus has a lot on they focus on that and they loose sigh ot everything else in the meantime.
taurus take such a long time to get comfortable with you that a month to you is like a week to them so you could be waiting endlessly and still nothing appears to move but they y reserved andmay not be confident with you yet,
but if u hound themwith calls and texts that wont help anything.
if anything it will annoy himand also trying to get answers forcefully and trying to get them to make up their mind or giving them ultimatus
and getting annoyed at their lack of responce turns them off but im not sure if u are dating,
just seen him and likeing so its hard to answer the question but i hopr this reply has helped since nobody
hope u have the patients because u could be ignored for even a year if his life is upside down or if he has issues t deal with or kids but if he has recently seperated from someone and that meabs a week to 2 or even theree years,
he will be slow,
depressed,and pondering on the things that went on which leaves litl room for anyone eelse has left u and answer.
