Taurus acting distant towards Scorpio - Should I break up? Is this fishy?

Ok, soooo about three months ago, I started casually talking to a Taurus (trucker) that I met online - not thinking it would get serious and was excited to banter with someone I didn't know.

The conversations ended up becoming hours long (3+). From July until September, this Taurus would call me every morning and every night to talk to me. We met up in August, continued our super long conversations and a week later he told me that he loved me. If any of my friends told me this story, I would think it was insane! but...I believe his feelings were genuine and I was starting to feel the same.

We entered an exclusive relationship and have met up and enjoy each others company.

The confusing part is that for most of this past month, his communication is extremely inconsistent. He no longer calls me in the morning or at night. He seems very distant. I've called him out on it in a very logical way and when I do, he own's up to weird behavior and promises that he will make more time for me.

To give him the benefit of the doubt, he's had a lot of work, family and social circle issues in the past month that he won't go super into detail. He's been vocal about being stressed. I do think it's still genuine when he says he loves me. However, I sometimes feel like I am bugging him.

I've tried being super understanding and not bugging him or running into jealous conclusions (which my scorpio mind is totally panicking about).

In your experience, is there something fishy going on? Are Taurus usually like this (randomly distant)? Should I just call it quits or am I overreacting? Do you think he's cheating (doesn't seem like it on his social media though). Most of all....how can I help?

I really value this relationship and I haven't felt this strong of a connection with anyone so I kinda want to make it work but also want to be realistic.
