I'm desperate for input/help from someone who has cyclothymia or from someone close to a person with it. I met a wonderful woman, and began dating early April. By late April, we had "the talk" and agreed to commitment and monogamy (her words, her conditions, and I happily consented). She lives 1.5 hours away, has a young child, and works full time, so each weekend and nightly phone calls were our time spent together. She: 30s. Me: a bit older. Until mid July, it was bliss. I'm not kidding. Bliss. Emotionally. Physically. Everything. We both talked and laughed about how good and compatible and smooth things were, and how great things were between us. This woman was the picture of consideration. She always called me back. She did what she said she'd do. She was ultra-considerate. She was open and communicative. She was close to perfect. Then her mom was hospitalized with kidney failure in mid July, had emergency transplant surgery, and my girl dropped off the face of the earth. One week of a few replies to my texts (no phone replies to my messages and no outbound calls from her to me). I sent flowers. No reply. I left nice messages ("can I help you or the family in any way"). No reply. I left more caring messages. No reply. I texted thoughtful things. No reply. I found myself saying, "she's the polar opposite from the first 100 days". I then recalled that during our first phone call, she told me her mom had Bipolar One and abused her and her brother when she was a toddler (witnessed by another adult family member), and was treated with hospitalization and meds. The mom was also hospitalized later for a year or so when my girl was in her teens, and then rejoined the family. I know that BP is likely hereditary. Do people with such afflictions "disappear" without word or warning? She did not quit her job as an award-winning educator. I doubt her son is being ignored. But me? I've been abandoned, ignored, discarded and deserted without warning. After one or two dates, I could understand the disappearance. But, after months of intimacy, bliss, and memories (we had gone away on mini-roadtrips several times, were planning a longer island getaway, and even a trip to Asia next year), I don't think I was duped and being lied to and don't think there is someone else in the picture. She's too bold, honest, up-front and, quite honestly, mouthy, to not give her opinion with conviction if in fact she changed her mind about me. I don't get it. I'm sick with worry and beyond troubled and confused. This is really like a whole different person. Is this disappearance a cyclothymia symptom? I witnessed zero, I mean zero, depressive or other suspect behavior previously. Normalcy, upbeat spirit, groundedness, and priorities-in-order was all that I witnessed since April. I am lost and in pain. Can anyone opine?
