Thank you for being so honest about what is going on. It’s hard.
Now for a warning to you about this forum. Most of the people on this forum are BS’s. (Betrayed Spouses) An AP can see some of their comments to you as being harsh or mean. I assure you that most of the people I have come to know on this site are good people, with big hearts. Some may be outright vicious to you, but that will be the minority. Ignore them or block them.
I am very sorry to hear you have found yourself in this awful position. As you mention a couple of times, there may be some cultural differences that we are not aware of. Be clear about those. Beyond the arraigned marriage, which I am confident most of us understand. You live in the US now. And despite what you may be watching on TV currently, this is a free country. We don’t force anyone to marry another against their will.
You now find yourself as the OW (other woman). This is not a healthy place to be. Not for you, him or his wife. He left to visit home. He knew you before he left. He then married another woman. He made a commitment to her that he has NOT made to you.
He may have been nothing but truthful to you in the beginning. He is not a truthful person now. He is a liar. He is either lying to her, you, or both. And he is making you complicit in hurting another human being who has done nothing to you. And I assure you, no matter the circumstances of his marriage, that this IS hurting her immensely. She just doesn’t know it yet. When she does, it will be like a bomb going off in her heart.
You MUST end all contact with him. Immediately. You two cannot be friends. Imagine, how you would feel if he left his wife, married you and wanted her to still be his close friend.
I know you have strong feelings for this man. I know that it will break your heart to sever all contact with him. However, this is the best course for everyone involved. You are 25. You know your heart will mend. Yes, it will suck rotten eggs for awhile. But you will pick yourself up, get back out there, and find a better man because you will be a much wiser person.
There is no room in his life for you now. There may come a day when that is not the case. But that day will not be until AFTER the divorce papers are signed by a judge deeming their marriage over. You deserve to live a happy life in the meantime.
You say in your post that you know you want someone who will give you 100% of their love to you. You are a human deserving of nothing less. Stop settling for second place. There are a lot of men out there that would NEVER do this to you. You deserve better.
I would lastly suggest that you start seeing a counselor. Most everyone here has. You need to address why it is that you are even considering settling for less. We all have things in our past that has caused us to question our worth. Those issues must be addressed before you find yourself in the same place with another man.
I wish you nothing but the best life. In your heart, you know this is not it. Or you wouldn’t be here saying the things that you are saying. Nothing good comes easy. It’s an often used phrase that we ignore because we are human. The hard work is going to suck. But, I promise you, if you follow my advice and the advice of others here, that you will come out of this a stronger, healthier, happier person.
