Dam man stop crying (i'm in love don't know if she is in lover etc, etc.) You sound like you are in junior high. Sending money on a money plan???? So if I tell you I love you how long before I get on that plan.
Please, man up, dump her and start looking again. There are some good women in the D.R>
OR
Tell her you are going through a tough time and can't send any more money and see how that goes over.
If a women asks me for money my standard line is "I already have 4 kids and don't want another", period end of story.
