Hello Druidess,
A couple of things jumped out at me right away. First, I see arguments in the relationship in the past, possibly about family or friends (Whip in House of Dog).
True enough. Like any lengthy relationship, we've had our share of arguments, and sometimes they are about family.
I feel your partner is a tall man or an executive (or both) since he appears in House of Tower (with Whip beside this, a lawyer perhaps...family law?) who likes to hang out with friends a lot (Dog in House of Garden),
Tall, yes; and taller than me. He does social work, so is very much not an executive.

He does enjoy seeing friends, but we both tend to be "homebodies."
and also that right now there's illness but that the choices being made will have a positive outcome...however, this has unknown effects on your own health.
Well, right now I have an illness -- this darn cold that's been lingering for the past week. (Snowblowing the driveway does not help!) He hurt his back recently, so has to baby it for a bit, which is why I have to do the aforementioned snowblowing right now.
I take it you are feeling some isolation in the relationship right now as you appear under Tower in House of Heart. You're a charming and emotional man since you are in House of Moon...Tree in House of Sun shows me that your emotions run deep, but are usually positive.
I don't feel isolated in our relationship right now. In general we have good communication and openness. I like to think I'm charming.

And yes, my emotions can run deep. I suppose I tend to complain and look at things negatively, but am largely positive at core.
Attempting the Loop method, the relationship appears to be a long-established relationship, buthere are things that may be eating away at it (Lily in House of Mice). That appears to be told again below with Birds in House of Anchor and Snake in House of Cross...there are burdens and stress/anxiety here, but they are being discussed and dealt with together. These are the most important points I saw.
By loop method, do mean going from house to house to house? I used to use that as a core method, it worked well for me, but I later dropped it from my repertoire. I agree it's long-established. He suffers from anxiety which does affect us in some regards, yet we deal with it together. Of course it's a burden at times, to both of us, but we have discussed as it is an ongoing issue.
Nice work.
