About annulment

My wife always says she does not want me anymore she sent me messages about it and I found out that she is chatting a foreigner asking for. Sponsor and also she told me that someday she will leave me for somebody else. It's all in the chat message. Can this be a ground for annulment. ? Or separation

Also she keeps on loaning money I told her to refrain. From it and she told me I'm out of it. But she keeps on asking money from me. And if I can't give her she gets paranoid.
