Some great and valid points above. The WL-BF dating arrangement is a complex and interesting one, but when you skin this animal it generally looks something like this:

Chick
- She's young attractive and comes here to make as much money in the shortest amount of time.
- She gets herself a bf for (temporary) companionship, intimacy, and for the physical/emotional security. Afterall, she's still a young woman with hormones and emotions and needs to feel like a normal woman when she's not prostituting herself for a fistful of dollars
- She has no intentions in marrying or settling down with the bf, it's just a short term arrangement while she makes money.
- She'll generally have the bf wrapped around her little finger and with enough sex appeal she'll receive a ton of kickbacks, gifts and perks from the bf and the plethora of thirsty desperate punters that get their plumbing serviced by the chick. At this point she'll be stringing several blokes along (her rotation)
- She works 5 to 7 days per week 12hrs a day to maximise her earnings.
- Her so called friends at the shop are not really her friends but bitchy narcissistic jealous rivals; the only thing all these chicks have in common is that they suck cocks and get pumped by random old fat punters all day long.
- Rinse and repeat cycle but in a different area/country.

Boyfriend
- For the bf the WL is just a trophy girl, someone he can show off, take out to movies, restaurants, concerts, trips etc
- He gets free sex and maybe the occasional raw dog when she's on the rags.
- He has no intentions in settling down or marrying the chick ie she's just a prostitute
- If/when the bf falls in love with the chick (RED flag) that's when the situationship turns to a situation-shit, another words he is as good as fucked.
Note: Most of these arrangements start off as situationships, but if the situationship turns into a relationship it's the bf that generally ends up fucked financially, emotionally and psychologically.

Some other variations to the above include
- WL in search of a visa-PR mule (aka PR'oyfriend)
- These chicks are generally the older and more seasoned MILFs with a kid and some bad debts back home.
- The MILFs cannot compete with their younger sexier prettier rivals, and with time and age against them, they look for lonely old fat balding single/divorced retirees; ie blokes with money and assets (Note: looks, hair, physique, charm, hyegene etc are optional only)
- Once they get residency and the lifestyle they seek it's just a question of whether the old cunt kicks the bucket first or whether she dumps him first.

In some aspects it's a hard and sad life but ultimately it's their choice and their life; there's no wrong or right, just the consequences of their actions and their fucked up perspective on life in that money will make them happy
