<human>: I'll try to sum this up quickly.

Within about 6 months, I've found out that my bf (sort of) cheated on me (pursued other women (non-sexually) with no intent beyond feeling better about himself).

 I found out he has found me less attractive due to weight gain (I was about 180lbs/5'7" when we were initially dating (always been a bit chubby), currently a little over 200lbs). Trying to lose weight but not seeing much progress (maybe 5lbs down in several weeks).

I've always had a lower sex drive but I have taken steps to bring it up (stopping the pill, changed to non hormonal IUD). the sex has taken a huge leap backwards and I'd like to fix it.

He's been jobless and likely depressed for about 7 months which has affected both his own self esteem and my views of him.

Things have been really rocky for about a year now and were trying to mend everything but it's just been really hard to overlook feeling fat and betrayed by a boyfriend who is constantly whining and being depressed.  

How can I help this situation? Were both committed to making things better, but it's hard to feel ok right now.

Please keep in mind that although a lot of this sounds bad, We ARE really good together. You're only hearing the bad stuff and there are tons of other things in the relationship that are great.

Can you provide a brief overview of the text?
<bot>: jobless/depressed boyfriend betrayed me a while ago and now tells me I've gained weight (and therefore is less attracted to me). I'm having a hard time overcoming this situation.
