It finally dawned on me last night that Adam is an emotionally abusive boyfriend. He's charming during the pursuit phase, but then gets angry over perceived slights or entirely made up s$%# and forces Jenna to apologize and cater to him. Last night, we saw him giving Jenna a version of the conversation with Madison that had almost no relation to the actual truth. What his version DID do, however, was to continue to distance Jenna from the other stews. Abusers like you isolated from people who might speak the truth to you. On some level, Jenna seems to realize that he's emotionally abusive. Last week (or was it the week before?) she mentioned the problem with her choices in men and that it looked like it wasn't changing soon.
The both of them need therapy.
