Beautiful picture! Greg does not "look like" a slut puppy to me. He looks like a happy guy.

I don't think he would go to the work of coming to see you, marrying you (notice that Douglas did not choose to marry you), doing all the visa work and making a place for you here in the States if he did not want to be with you and spend time with you?

Maybe you are afraid of leaving the Philippines where you know people and the culture and how things are and coming to a new country? That's very scary, especially if you don't know anyone; I would join some "regular" groups online and meet other women, both Filipinas and others, especially some who live in the area you will be coming to? Talk to them about Greg and see what they think? Get some roots started here so when you get here you have people you have talked to online and can meet in person, maybe a church group, etc.

Another thought is to ask Greg for enough money to fly back to the Philippines if you have too much trouble getting use to the United States and find you really do not like it. Tell him you do not plan to use the money, do not want it for its obvious use but want it for emotional security while you are becoming use to his country. Tell him it might cut down on how many bad things you say about him, how much stress you put on the relationship trying to reassure yourself that it will all be all right because you will have the means to make it all right if you are disappointed.
