Hi Daisy,
My name is Steve. I also answer health questions here on JustAnswer.
I suspect that your fiancé's stomach problems are due to lactose
intolerance -- a disorder which affects many adults. Its cause is
the lack of a digestive enzyme, called lactase, which is necessary to
be able to digest the lactose (a.k.a. milk sugar) present in many dairy
products -- including milk and ice cream. Lactose intolerance is
easily managed with an over-the-counter 'dairy digestive enzyme'
product -- containing lactase. Just have him pop a couple of
those pills just before eating ice cream or drinking milk.
Regarding his irritability -- having two of your favorite foods
suddenly start to give you indigestion on a regular basis, is enough to
make anyone irritable. When you add on the stress involved with
his parents suddenly deciding to move to another state (even though
Idaho is very nice -- I lived there for 40 years) -- and, and also add
in the (good) stress of a new baby (which probably means
less-than-normal sleep) and even a Saint would be irritable.
While it is certainly possible that your fiancée may have some sort of
emotional disorder -- and it is true that not all people with bipolar
disorder have extreme mood swings -- I can tell you that bipolar
disorder has developed a reputation for being over-diagnosed.
I would recommend that you see what a few bowls of ice cream (without
an accompanying upset stomach) and a few good night's sleep (when that
becomes feasible) do for your fiancé's irritability -- before you buy
into the bipolar diagnosis.
I also recommend that you plan a trip to visit his folks in Idaho -- if
you tell me which area they are in, I can tell you what to expect when
you get there.
Let me know if you need more input. If not, thanks for the
opportunity to assist you... Please honor my efforts by Clicking the

Adding a bonus -- should you wish to do so -- would be warmly welcomed.
Good Luck!
Steve
