You have probably experience new phrases in your
preception of BGR subconsciously. Previously, what you deemed as
acceptable, changeable or even able to compromise, has evolved. The
biological and natural woman's 'investment' needs spring forth -
the greater need for financial-related-future security.
This is pretty normal (especially if you are Virgo, Capricorn or
Taurus).
Your last paragraph speaks of your possible options: you could
either try it out with the new guy or rough it out with your
current bf. However, pretty likely, I could see your desire to
break free from this relationship.
A partner fares poorer than u doesn't appeal to
u.
You are entitlted to the kind of partner you seek,
obviously if your boyfriend doesn't appeal to you and you are
remaining in the relationship for the sake of duty, responsibility
and probably due to length of time, something is really wrong
somewhere. You also note that this anti-seductive-passion-killing
thingy is all about you, while your boyfriend, is presuming, being
pretty happy in the relationship.
Nothing works one-sided.
Always attempt to save your ship before you abandon it, like what
the navy captain would do in event of a damaged ship. Repair,
repair and repair until you find that it's getting hopeless, before
you call for a abandonment. IMHO, you haven't reach to that stage
yet, then seek out proper communication channels to discuss these
sticky issue like matured couple.
You MUST let him know about your dis-satisfaction about the current
bleak future and MUST either motiviate, propose a mutual solution
or both. From there, you will make your own judgement. 
Cheers
