<human>: We have been together for 1.5 yr, broke up 2 weeks ago.

He felt companionship with me, but romance to another girl. He decided to go with his heart and dumped me. He said he felt comfortable, happy, loving and safe with me. He thinks that I am beautifully, smart, funny, tolerance and forgiving. He never met such special girl that has such nice personality. We seldom argued. He said that I am the dream girl of him, he likes the sex we had, the great care and love I gave him. 

But one day he met this girl (his colleagues, I only know that she is elder than me), he felt so strong romance with her. He said he cannot stop think of her, he wants to be close to her, do romantic things with her. He said he never had this feeling in his life, he wants to feel this passion, at least once in his life, even if this means he has to give me up. 

I was so heart broken. I explained to him that passion is just an illusion. He said he has to try, he must do this, 31 years in his life, he never felt so passion to someone. He also was honest to me about his feelings that he wants to explore, hopefully can have a future with her, so he wouldn't regret to split with me; he also told me that he still loves me and misses a lot, he is scared of losing me and scared of regreting giving me up. I understand how he felt, I am not mad at him at all. My heart hurt so much knowing he likes another girl, but I know I have to show my understanding.

Can you provide a brief overview of the text?
<bot>: Please give me some advice that how I should face him/handle this issue (I think he loves both of us, but in different ways, if I didn't misunderstood)
