yes
It is always great to have a close friend that you can depend on and trust.
My friend always gets involved in helping others. The plight of the poor will become more meaningful to you if you will become involved.
There is nothing special that you have to do to support your friend who thinks she might be lesbian. Just be her friend and have the same relationship with her that you have always had.
When you meet someone new and they tell you that you would only be a friend to them this means the romantic chemistry is not there to have a relationship together and you will have to accept it.
No. This can cause relationship problems between you and your friend. Friends are always better than crushes.
No matter what the relationship is between your crush and your best friend, you should NOT go out with that person. There's always the potential for jealousy from your "friend" and it could ruin you alls relationship. There are plenty of fish in the sea.
I have to admit I am very puzzled and what opposite sexes consider friendship and being lovers in a serious relationship. I've had male friends when single and we had great fun together without sex involved. I am not accusing you that you are having sex with this person, but, you did say 'committed relationship.' Keep your friends as friends and save the sex for the love of your life. If you haven't had a sexual relationship then no, it's not wrong to spend the night with your friend. You can always sleep in another bedroom or on a couch.
You can have a friend that a girl or she can be your girlfriend. This depends on your relationship and how you treat each other. Friends aren't romantically involved.
He wants to be your friend, but is not interested in being your lover.
You can put anyone you want in your will. Blood relatives may cause a problem depending on relationship and the amounts involved. Peoples true natures come out when a will is read.
You should not let your friends affect your relationship with your best friend. It is sometimes a sign they are jealous of your relationship with her and they want what you have.
Think about what would be best for all the parties involved. What would be best for you? What would be best for "the guy"? and most importantly What would be best for your best friend? You do not want to ruin the relationship with your friend because of another relationship that might not last very long.
