So back in August last year I moved states and left my boyfriend/FP to better my mental health and live with my mum (FP and I were together for over 2 years at the time I left). It’s been hard and every time we see each other it is perfect then I come home and I have a mental breakdown for a week straight. 
For the last month since I saw him I’ve been obsessive and constantly needing his validation and messaging him 24/7. 
He’s on tour with his band currently and yesterday asked me for a break because he doesn’t want to respond to me, message me or anything and just doesn’t miss me because he feels he looks after me and can’t cope with it ontop of his life and mental health. 
He’s asked me not to speak to him a few days and unfollowed me on Instagram but still has my name in his bio.
I snapped and messaged him saying that upset me.
I constantly check fb, ig to see when he was last active and I know it’s an unhealthy habit. So I’ve deleted all social media apps besides reddit from my phone to stop the impulsiveness.
Last time (a few months ago) I deleted social media he decided to follow some girls he was talking to before me and liking very provocative photos and I saw when I lurked and reactivated them.
He blocked them and we spoke about it and he was honestly sorry and he never spoke with them just followed on social media.
I do believe him because he’s not that sort of guy and he’s given me all the proof I’ve asked for.
But I still tend to check his recent followers/following to make sure he doesn’t do it again.

My ex of 4 years before him used to cheat all the time so it just piles on the fear of abandonment.
I just can’t move forward from it and it’s made me obsessed with him to the point that we’re now here on our break. 
I move back home in a few months but has anybody been able to do long distance successfully? 
What are some tips or coping mechanisms? 
How do I go about not feeling like I’ll be cheated on and abandoned? 
How do I cope if he comes back to me in a few days and says he wants to separate? 
I’m trying to prepare myself for it but besides MY bpd we are so perfect for each other and we have such a loving relationship.
Moving has just ruined me and built up a lot of my own issues from my past. 
I was seeing a terrible psychologist who would sit on fb and show me her house and not actually talk to me about shit.
After last seeing FP and my breakdown I decided to see a new psychologist and I love her so much she is amazing and fully understands bpd and always empowers me to be better.

I’m on stronger medication, going part time at work and going to ask to see my psychologist weekly now. 

I’m sorry I just don’t know where to go or what to do and I just need someone, anyone.
