Can’t live with him or without him ?!?

We’ve been dating 6 months and honestly he’s the one. I see me marrying him, moving in together, spending every waking second with him. i can’t imagine loving anyone more than him as none of my many ex’s ever came close. Even when we fight we end up laughing after. He has helped me so much with certain parts of my mental health i can’t imagine being without him. We already basically live together and everything feels like an actual fairytale....but. He has severe anxiety and insecurities that cause him to be over protective even when he knows i’m loyal. Every once in a while when i’m out with friends i get non stop phone calls and long texts about how i’m not answering quick enough or how i answered the phone weird or asking who is there with me. This only happens every once in a while when i’m out in a group with guys in it and he always apologizes after. It gives me anxiety cause i feel like i can’t have guy friends and he always flips out for no reason. But it keeps happening no matter how many time he says he’ll stop and work on it. I know it’s because he’s been cheated on so many times but i’m tired of feeling untrusted.

By night out with guys i mean i was getting food with some old friends and 2/4 we’re guys. So it’s not like i was going clubbing
