Hi there Sisu and welcome to the forum
I can only give you a reflection of how I have behaved in my previous relationship, as someone who has been recently diagnosed with PTSD(which was with the first guy I have ever loved), as some guidelines.
Sometimes I would push away, but expect my partner to realise that I wanted him to fight for me, not to just walk away and leave me to my own devices. I guess testing the boundaries! However, sometimes I would actually need the time to decipher how I was feeling - I guess a mail or a text that just says
'hi I am here if you need me' would be enough to alleviate any anxiety over whether you are going to disappear on him?
I think you can only tell this guy how you really feel when and if he gives you the time to do that?
I Love you,
I am here for you, I will support you, but I will not be an emotional punch bag, you/he need to take responsibilty for yourself, I care about you, you get my drift? Being supportive but not allowing him to use his PTSD as an excuse for his behaviour. He has to own that however, he frstly needs to see these things, you can't do that for him.
PTSD is a hard battle with so many complex issues that affect the sufferer. However, I do not beleive that it means you cannot be loved or love, it just means that the realtionship maybe harder than most at times. You both have to be open and committed.
You need to ensure that you are strong for you, have good clear boundaries about what you will and won't accept!
There are some good clues on this forum as to how a sufferer feels and interprets thier world. Not everyone is the same but it may help you?
Shop around and see what you can find?
My thougts are with you!
