Mercury in 8th House Synastry Explained
Mercury in 8th House synastry partner may not understand for a long time why you often take his words so personally; however, you may not understand this either. But he will most likely have the gift of pissing you off with just a few words, intuitively guessing what’s most important for you. Not that it was easy for this partner to really help you with advice in an emergency (this is achieved only after the synastry has been worked out, leading to the partner’s deep understanding of the circumstances of your inner life), but such a temptation will arise from the very beginning of your relationship.
At the same time, for you, the Mercury in Eighth House synastry partner will rather be a messenger of twists and turns of fate. However, you need to avoid thinking that he is causing them, and even more so not to blame him for your failures and breakdowns, although this temptation can be significant, especially with a strong partner Mercury, when the latter is inclined to comment, discuss and give advice in all situations. Then, of course, it is difficult for the partner to understand that his words have much more significance for you than for everyone else.
You also need to be very careful about your Mercury in 8th House synastry partner’s financial proposals. If your ethics system is flawed, such proposals will quickly affect your finances: put simply, trying to get rich quickly will open you up to misfortunes. At the same time, the partner can wriggle out, but, of course, he will console you as best he can, for example, with witty jokes as you find yourself in a lot of debt.
