I've been dating my boyfriend for 5 months and he's a great guy. We treat each other well and there's never been any real problem
But as of late, things are hell for me.

My BPD flares up every few months and things get bad, but I keep it all in and pretend everything's normal so I don't fuck anything up.
The past few weeks I've really taken notice at how bad he is at listening or helping when you talk to him. It's hard to talk to him because it feels like he's not there. 
It's the same thing every. time.

*"I'm sorry."*
*"I wish I could snap my fingers and make it all go away."*
*"It's okay, I love you."*

Now I understand you all might think I'm an ass for this- because at least he says something, it could be a lot worse.
But after a while, it feels like a routine. I have a hard day or someone's bitchy to me or anything bad really. He'll ask about it, I'll tell him, and one of the three quotes is said.
He puts little effort into texting, and since we only see each other in person 1-2 times a week, texting should be taken a bit more seriously right?

I addressed this to him both over text and in person. Over text, his excuse was *"I'm sorry, I've always been bad at texting."* And a few paragraphs about how he needs to change and he's glad I brought it up.
When I brought it up in person, he was quiet for a while and I could tell it made him feel bad, he finally said "I don't know what to say, you're right.. but I'm going through the same shit and I just don't feel qualified to help you.".
Of course I felt awful and told him I shouldn't expect him to be my therapist and that I should look for professional help myself. I kept apologizing and he was forgiving as always. 

He doesn't talk about how he feels much, and it seems like he's just disconnected with his emotions. 
So my brain says *This won't last, you should break up with him and find someone who cares, he doesn't love or give a shit about you.*

And then I start to get insecure and feel as if I've gotten myself into a place where I'll be miserable.
I was fine with handling this before, but it's been bad lately to the point where I don't know if I want to deal with it in the future.
It's fine if I'm being selfish or there's something that prevents him from being more open and I'm just inconsiderate of it. But he won't EXPRESS IT. Same thing when something exciting happens, it's as if he doesn't care.

Is BPD taking over? Or am I in the right?
