Hi all
My bf suddenly left me while we were planning our engagement... I suffered a lot... I felt that my life is over.
I believe (as well as two of my friends who are psychologists) that he has BPD. I would really appreciate your opinion
Some signs I saw that make me think he has BPD:
1. The beginning of the rs was
intense. He was calling me ALL the time and he wanted to be with me ALL the time. I felt like i was suffocating.
2. During the first two months of the rs he was getting really upset and he was
shouting to me every time I was chatting on social media with guys (good friends) or my ex (again, good friend)... He was getting angry and breaking up with me like once a week! He even told me "you are worth of NOTHING" once. However, all the anger stopped when he started taking antidepressants and tranquilizers (for his panic attacks)
2. Within two months of the relationship he told me that if things go well he would like to get
engaged soon and he suggested that we can try, if i want to, to have a
baby 
3. I noticed from early in the relationship that he had weird
mood swings. For example, morning: he was sitting very quiet smoking and didn’t talk to anyone, including me, and evening: he was singing to me in the car REALLY loudly and he was dancing and tooting to other cars without reason
4. Last January (we were together for 10 months), he saw an innocent msg from my ex bf that we broke up mutually – asking me how am I. He got really upset and left from my house. Since then, everything changed... For 2.5 months he was trying to leave me while at the same time he was trying hard to stay... (
push pull i guess?)
It was the most weird thing that happened to me... .he was telling me ‘’The problem is not love... is happiness... i don’t feel happiness’’ or "I don’t want to lose you but I think I need to be on my own’’. He kept telling me ‘’give me some time alone’’…The next day he was calling to see how am I…Then again “I need to be alone” and the next day ‘’I’m scared if I leave you I will regret it that I did the worst mistake in my life’’

3. During these weird "push pull" months, he also developed
severe erectile dysfunction that didn't seem to go away (he is only 27) and his physician told him that and the problem is clearly mental
4. When I got so sick and tired from his cold and distanced push pull behaviour i decided to take a step back and continue my life... .I thought "if he stays, he stays"... i cannot be sad and worried anymore. When i did that and
i stopped giving him attention - he came back full force! he became the same loving bf he used to be, he started telling me about weddings and babies again, and the erectile dysfunction disappeared!

5. Exactly 1 year after the first break up….just 20 days before my masters degree ends and we can move in together. He suddenly became really anxious that I don’t want to marry him. He kept saying “you are not ready to commit, otherwise you wouldn’t wait for the masters to finish you would move in right now” and AGAIN in a few more days “I feel I am suffocating, I feel sick, I am not sure if you want to be with me and get engaged” (
projection/fear of intimacy?)…”This relationship doesn’t move forward. We have to get engaged exactly the day you finish your masters or that’s it” “enough”. I got angry and I told him that he cannot pressure me like that and that he acts really weird whats wrong with him?
6. And…... the next day he broke up with me. He told me “It is not love. Is happiness.
I can’t find happiness. You don’t make me happy, I was never happy in my life” and “get over it and continue your life” “I don’t feel anything for you”. I have tried hard but he was cold. Distanced. He was a
100% different individual.
7. Seven days after we broke up my cousin saw him in a restaurant with a
NEW gf and HER family (I got replaced!)
8. I found out that when my ex was young (around 14-15),
his mom had an affair... my ex didnt know... and when he got home early one day from school,
he caught his mom having intercourse with her lover. In their own house (I guess this explains a lot?)
9. Other BPD behaviour i noticed: He was
worried all the time that i will leave him for someone else and he was
threatening me "if you ever leave me for someone else, i promise you i will make your life a living hell" or "I'm worried that i am wasting my years with you and you gonna leave me". Also, sometimes he was pretending that he was fainting. And he was telling lies.

10. Finally, i found out that he was in a
serious relationship with a girl before me for about 1 year, when all of a sudden he told her he doesn't love her anymore and he was with me in like 10 days.
