Need some advice

So this is not reassurance seeking but basically me and my boyfriend are long distance but not too far (an hour flight) but it means that we’ve been seeing each other every two weeks which was hard in itself because I have a pretty high attachment style and the OCD makes thing super hard too. He feels like he has no routine with the flying back and forth and he wants to push back to only seeing each other every 3 weeks (me go there, then 3 weeks later he comes here etc). This has caused huge arguments over the past few days because I know I’m going to struggle with this so much with the OCD. I still have HOCD / ROCD when with him, the thoughts and anxiety don’t go but they’re way worse a lot of the time when apart and they get progressively worse the longer we’re apart so this situation is really triggering and upsetting me I haven’t stopped crying for days and then in turn I get quite nasty with him and he doesn’t understand. I don’t know how to move forward with this and be happy with seeing each other so infrequently with no end in the near future (neither of us wanna move to the other for at least another year or two). Any help with how to deal with this would be appreciated.
