I WhiteMoonvenus is square to pluto with pluto on the descendant. this is a difficult aspect for a relationship because the emotional sensitivity is not equal to the physical attraction .pluto shows a high degree of selfishness which usually does not bond well in relationships .initially this aspect does give a extremely potent sexual chemistry but usually the sexual desire falls off for one of the partners after the emotional intimacy does not become stronger with increased sex, loses interest in sex . this does not preclude a relationship, but the relationship will not keep the sexual intensity and often celibacy is the result. I have seen marriages with this aspect that survived but there was nota sexual life.
this may be surprising because the mars/venus midpoint is square to the psyche/eros midpoint which is just about as emotional/physically attractive an aspect as you can get, as this combines physical love/sexuality with a "higher", idealistic,spiritual, romantic connection.
with the satrun/moon midpoint square to mercury, there seems to be a acknowledgement of a feeling of steadiness between you.with mercury conjunct the vertex,it seems that you have a very strong mental connection.
in addition the Jupiter/juno midpoint is square to the vertex also, so there must be feelings 0r at least talk that the relationship could become serious.
my feeling are than currently the relationship is not going well because the mercury/Uranus midpoint is square to Saturn.
and currently the node is conjunct to Saturn which suggest he is having second thoughts about this relationship or he is being distant and and non communicative .
it is possible that arguments or differences have broken out recently also.
