Purpose this all seems like a hard situation for you.

It seems to me reading this that there are a few things you might want to ask yourself. Like how do you feel about his declaration of love for you? Do you see him as only a friend? Or do you feel the same?

I think the main thing though is that as hard is it may be you cannot take on the burden of his words or actions. He is in his relationship by choice, and he has said these things to you by choice. Only he can make a change. Of course you feel bad, of course you worry about him and his girlfriend but his situation is of his own making and so nothing you can do or say will fix this for him. That is an inside job for him to complete. There is nothing wrong with being a good, supportive friend if you think that is needed in this situation, but it’s important to keep your boundaries in tact and not allow his stress and drama to pull you into the middle.

The most important thing I’ve found that helps me in situations is to stop rushing and worrying and trying to find the perfect answer. Do nothing, just sit and be and let your feelings come in and pass through you naturally and freely with compassion. Then when you feel calmer check with your intuition what you should do. It will be the quiet voice whispering to you underneath all the mind chatter and loud external drama.

I hope this helps? Sending you all the best.
