Am I In Love?

I am 25, a year ago I broke up with my boyfriend, 2 years of relationship and I accepted the separation very hard. I was a student in another city and I decided to stay there. Things were difficult and I decided to find a roommate. It so happened that an acquaintance my friend also had a job, we saw each other, got along and took a place to stay. to clarify that everything was completely normal. we had 2 bedrooms, it was never any sexual innuendo or something like that. so..we lived 4 5 months, mm fast time passed, we became friends, we went out together, everything was great. I really got attached to him, he helped me get out of depression, how can I tell you, the fact that he was there and I wasn't alone helped me a lot. I'm a cold person like that and I didn't tell him how grateful I was to him. I was dealing with other boys during that time. time passed and the landlords asked us to vacate the apartment,he was wondering what to do, whether to be roommates together again, to go home to his city or to be alone in a dormitory. today he decided that he would go home to his city and e at we will not see each other to say goodbye, I was at work, my tears flowed all day I thought how well we understand each other and how it would be the perfect relationship, but I just missed the attraction, the chemistry. please help me, am I in love with him or I'm just afraid to be alone, I want to be with him every day, fun is good is never betray me.but I just missed the attraction, the chemistry. please help me, am i in love with him or am i just afraid to be alone, i want to be with him every day, fun is good is never betrayed me.but I just missed the attraction, the chemistry. please help me, am i in love with him or am i just afraid to be alone, i want to be with him every day, fun is good is never betrayed me.
