Sorry I couldn't confused them. Let me look with new eyes.
editing this as I go:
His Sun (his ruler), Uranus and Mercury and hit your 4th h. I think you feel like home to him. A constant he feels he needs as in a habit. Talking, communication.
Energetic. He might bring nervous energy when not in person.
3rd (communication) The Libra energy his Pluto, Jupiter and Saturn
is what you're feeling. He might be controlling, you feel it. Libra can be demanding and you have Saturn and Pluto coming through him. Severe in nature.
As though he wants a schedule or to keep tabs?
In Scorpio is your Pluto, the nature of obsessed energy but it could be directed at you not from you. . He's attached and has expectations of you
...
The composite with the Saturn sextile Jupiter makes me think (Saturn in Scorpio) yet the 3rd is ruled by Jupiter. He's coming through as though he has a strong sense he feels he should have authority. Maybe entitled to your time in communication. He may fear if it's not him - then who?
Your Saturn is ruled by Sagittarius. This tying you together. From the sounds you enjoy him. He, imo might want you exclusive or really wants you to invest in the communication ways available when not together.
