Following girls on a night out

My boyfriend recently moved across Australia with his father and once he gets a job I’ll go up for a couple holidays, make sure I like it and move with him. That could take a bit of time as he can’t get a job till he gets his motorbike licence renewed (he lost it for 3 months for having THC in system)

A couple days ago he made a new Instagram and Facebook because he’s had his previous socials for years and they’re full of people he doesn’t want to follow anymore but his ADHD won’t let him sit there and unfollow/unfriend 😅

He was a big party guy/drinker here in Tassie and back where he is now he’s trying to do other fulfilling things, like fish or whatever else.

But the other night his dad introduced him to an older couple who gave a son a bit older than he is - that son had some beds for him in town so he was with him and then he and his friends went out drinking & dragged my boyfriend.

He did actually try to leave at 10, called realised it’s a sketchy town, and needed his money to sort his bike next week so he didn’t want to pay a cab so he went out.

I went to sleep at 11 pm and tbh I’ve had some traumas from a previous relationship that lead me to look on his Instagram. Again, he only follows like 10 people so it took 2 seconds to see he was following a girl he didn’t know before, who is now following him. He also liked her last posted picture which was her in a bikini at a beach. He’s not really followed any guys up there yet so I’m stressing 😅 it’s not like he’s following a bunch of people he has met. I’m not worried he did anything with this girl but I do suspect he had a nice ol chat with her

When he replied to my goodnight message he told me they were leaving the pub now and then at 2am he sent me a snap back at his in bed saying he had a terrible night.

He’s very loving to me and he wants nothing more but for me to move with him. He has told me he is even scared that I won’t like it. 6 months before he left we said that if I don’t like it we are shit out of luck but now he’s said if I don’t like it we will move elsewhere and try something else.

What do I do? Do I say anything 😩😩 I just can’t have that kind of stuff happening bc I’ve allowed it before and 2 years later I’m still hearing that he’s (my ex) a serial cheater, he’s given girls chlamydia, mentally and emotionally abusing girls and whatever else.

I don’t care if it’s crazy I am just protecting myself
