"Directing" thoughts towards a tulpa is similar to - if you've ever simulated a possible conversation with another person in order to try and predict how it will go.
You "speak towards them" in that simulated conversation. The difference here is that you are speaking "towards" your tulpa and not making up their responses.
So me constantly thinking about her and daydreaming her and talking to her every five seconds, along with singing her some love songs, including her in my art(drawing her) and just imagining us together is enough?
Learning to impose could work as a substitute - but that is quite a bit more work, and... quite possibly not healthy if you are trying to use your tulpa as a substitute to direct physical interaction.

In fact, I would go so far as to say that it is explicitly unhealthy.

As mentioned before - please don't use your tulpa as a reason to cut off or otherwise cease interactions with others.
They could mean that you are putting in mental effort that your brain isn't used to - or, it could mean you're getting sick. Or have been talking on here for too long (as quite a few people here likely experience, I would guess).

It could mean something positive, or something unrelated.

At the very least... I wouldn't say it's worth drawing a conclusion from in absence of something more definite - in which case, the more definite reason is worth it.
Try to identify your normal thought patterns. What "sounds like" you, what kinds of emotions do you normally feel, what do intrusive or unexpected thoughts (if any) sounds like. Then just listen/feel for something different from that.
Typically, one can draw conclusions from responses with time as they become more solid and capable of providing sure responses - it does take time to accurately recognize it (just as it takes time for the tulpa to develop their own independence).
At some point, you're going to get a response. It's not going to come accompanied by a choir of angels and a giant finger pointing to her, so you need to figure out how to accept whatever you do get.
