Hello Ariana: I noticed this is your first post here on PC. So... welcome to PsychCentral! I hope you find PC to be of benefit.

I think you received a solid suggestion from Bill3. You asked how you could know if this man loves you despite what he sometimes says. The short answer is... you can't. There is simply no way to know what is or isn't going on in your friend's mind. The other thing to take into consideration here, though, is you only have control over yourself & what you do. Likewise this man you have an interest in is the only person who can control what he does. (You can't save him from himself.)

You didn't mention (perhaps you don't know) whether or not this man is actively treating his condition. (You might want to ask him if you feel you can do so. If he says no, that may be a bad sign.) Being in a relationship with someone who is bipolar can be tough under any circumstances. If your friend is not receiving proper mental health care, this may only make things more difficult. And so what this may all come down to is simply... do you care enough about this man to be willing to accept all of the uncertainty & confusion being in a relationship with him may produce. Only you know the answer to that question.

Here are links to 6 articles, from PsychCentral's archives, on the subject of being in a relationship with someone who is bipolar:
