I’ve now been in my longest relationship – how do I navigate?

r/

TL;DR how do i (f24) navigate this new feeling being in a longer term relationship (6months) with my bf (m27) while also realizing the fear I have of losing them.

Me (f24) and my bf (m27) have been together for 6 months now. We met about 2 weeks before we started dating and he asked me to be his gf. I have never moved so fast with someone. I have had 3 past relationships all of whom I knew the person for around 2 years before we started dating but none lasted more then 5 months. I felt like once they had me – they didnt want me anymore. But with him it was so so different.

He has calmed my anxiety from the very beginning. He is the most reassuring person and never lets me doubt that he loves me. He is so understanding and kind to me and treats me like a princess.

But now I feel like I am in completely new territory. With him I can see myself settling down (and we have discussed as much such as if we saw ourselves with the other for a couple of years – we both said yes, can we see ourselves marrying the other – we both said yes, can we see ourselves having children down the line – we also both said yes) so he seems to feel the same. But I have this huge fear that someday he is going to wake up and see that I am not worth it, that he wants something different, someone new.

I should mention that I am his first girlfriend. He has liked girls in the past but to my knowledge none of them got past the one sided crush phase.

But im so scared that he will want something different, or that I wont be enough. I know if I told him this he would reassure me again and say how much he loves me and how much he cares for me and how much i mean to him, and its not like i dont know this – I am just scared of that changing. I know its in part due to my own anxiety and ocd for wanting to know for sure, but how do I help myself navigate these feelings.

and even at 6 months – i never run out of things to talk about with him. We are long distance (just by about 4 hours) and are able to see each other around every 2 weeks with how our work schedules are. We talk every night on face time and we are more comfortable then ever – or at least i think so. I feel like we are now really turning into best friends that truly understand the other. And that feeling is amazing but also very very new to me since all of my past relationships ended before the “honeymoon phase” was done.

I guess the bottom line is – how do i navigate this new feeling being in a longer term relationship while also realizing the fear I have of loosing them.

I would appreciate any advice but also ask that you be kind please.
