Let me preface this by saying that I am in a closed, polyfidelitous throuple/triad. My husband and I have been together for 5 years, married for 2. We recently started dating the boyfriend in March of this year. He told us point back, early on that he has BPD but didn't really go into specifics. This was during one of his out-of-the-blue breakdowns where he tells us repeatedly that we're going to leave him.
Aside from that one breakdown, the rest of the first month or so were great. He was very clingy (which I appreciate in a partner), and great. He would literally want to spend hours with us (we say one night until 6am just talking and cuddling). It was really great.
Then our first argument came about. One day he got out of the shower, still wet and in a towel and took a snapchat photo and sent it. I assumed it was to myself or my husband, but it wasn't. I asked him about it and he said it was to his guy friend (who they've had somewhat of a history, but only casually flirt now). After he blew up about it and then calmed down and we talked through it, we came to the consensus that it wasn't healthy or ok to send flirtatious snaps like that to old "f buddies" or exes. And he agreed and volunteered to delete/block the guys he was snapping. Which he did, despite me telling him he did not have to.
Fastforward, he seems very emotionally unavailable at times.My husband has chronic suicidal thoughts that recur every once in a blue moon. One happened one night while we were picking the boyfriend up from work. My husband asked if we could stop for a minute and talk it out. The boyfriend responded with "Ok, but not long. I am tired." So, my husband sat for a few minutes we took him home. The next day, he asked nothing about my husband all day. When we picked him up from work, he just kept complaining about his day, his sales, how nobody in the department talks to him, etc. When I finally mentioned that the husband was feeling better, the boyfriend responded with "about what?" Completely clueless and self-absorbed about his own issues.
He also never wants to spend time with us anymore. We take him to work and drive him home, and it's always "I'm tired, I need to go home to go to bed." And then he goes to his friend/cousin's houses and smokes weed for a couple of hours before finally going to bed around 1 or 2 in the morning.
He did have one idea for a date night where he would take us on a date (since we're always buying his food/taking him out). He said he would when he got his first paycheck at his new job, and didn't until his 5th paycheck. That morning we went and got breakfast, then he was suddenly "tired" and wanted to go home to take a nap. Instead, he went home and went to his cousins and smoked weed. While ignoring us the entire time. When we finally did go on the date that night, he kept making mention of eating cheap or possibly sharing a plate of sushi with my husband (they like sushi, I do not). Ok, fine. I get money. That's no big deal. But literally the next day when we picked him up from work, he had bags of clothes he had spent $200 on for himself (literally just three items of clothes). So, that kinda irked me and seemed selfish in a way.
We go in and out of our way to provide for him, take him on dates, etc. We took him on a $1000 trip to his hometown, where he showed us around and we met a ton of his friends. We were excited to do so. A couple of weeks later, we took him to our hometown and he was on his phone the entire time. Then he made us cancel dinner plans with a friend we haven't seen in months so we could take him home early (three hour drives), because he was "in a mood." Then, when he got home guess what he did? Went and smoked weed and ignored us for the rest of the night and almost the entire next day.
He is very hot one minute and cold the next. He does really sweet things at times and wants to hangout on occasion (rarely it seems now). And I'm kinda getting whiplash from it. I know with BPD, at least from what I read, they can split a lot. And I was wondering if this wax an example of splitting or just being a douche who has gotten too comfortable in a relationship?
Any advice would be very much appreciated!
