I think I'm in INFP in some potential danger and I could use some advice!

So I've been dating this ENFP for about a year and a half now and things have gotten pretty rough (I feel like I should add that he just tested ENFJ last week).

It all started when we moved in together. You know how we INFP folk get SUPER attached? Well, that happened. This guy and I bonded rather quickly at the beginning of our relationship and then--what seemed out of nowhere to me--the bond was just gone. He stopped paying as much attention to me, started getting frustrated with my need for someone to sit and listen to my ramblings, and basically stopped all emotional support. Right at this time, he became really good friends with one of my classmates and started inviting her over all the time and giving her all the love and support that he once gave to me. I feel like I'm invisible when she's around.

So naturally, I got jealous. I never got to really spend time with my boyfriend and it was driving me insane. Not to mention the inner conflict resulting from jealousy toward a friend. So things got worse and worse and I tried and tried to fix my problem on my own and it just wouldn't go away.

So right before thanksgiving, we had a huge fight and it resulted in me getting kicked out of the apartment and putting the relationship "on a break". And let me just say that all of my issues are now intensified and I am more sad and lonely than I have ever felt before in my life. I feel like I got cut off from the family that I was once a part of and that their lives are all going on and I'm getting left behind and no one even notices that I'm gone.

So I'd like to hear what my fellow INFPs have done to cope with such heartbreaking situations because I'm not coping well at all and I'm really scared about everything right now.

tl;dr My ENFP boyfriend kicked me out of the apartment and I need help coping.
