A relationship with two people is hard enough, having a third in the mix is troubling and complex regardless of sexual orientation.
u should keep the relationship as godly as possible and don't change for anyone
if your girlfriend cheated,you should end the relationship
No. She is your WIFE. You shouldn't include other people into your bed.....that is WHY you got married.
Yes
Learn all you can about bisexuality. Figure out what bothers you about this. Jealousy? Doubts about your own appeal to her? Fear of the unknown? Decide if you care enough about your girlfriend to stick with her.
* You said 'like' which could mean friendship or you are interested in him for a possible romantic relationship. Since you know he is gay or at least bisexual and assuming you are straight, then the relationship would probably not work out. One also has to be extremely careful of sexually transmitted diseases. If you are sure he is gay or bisexual it's best to keep a good friendship going and don't get romantically involved.
then she is not comitted to the relationship and you should dump her
If she does not like you, why is she your girlfriend. She should not just 'like' you, she should 'love' you. If this is not the case, I would break up with her. Love is the foundation of a relationship. If there's no love, there's no foundation for a relationship.
Well, you just treat this ex like any other ex of any other girlfriend you've ever had. Tell her to back off (nicely but with authority) like you would anybody else
The question should be how do you build a relationship. A relationship is built through trust, commitment and love.
Relationship is action and reaction. Try and know what your girlfriend likes and dislikes, use this as a guide to behave with her.
No, it's not. A relationship is based on trust-you probably should talk with her about what bothers you and you two should work on your relationship.
