Girlfriend texting ex

30m been dating my girlfriend 28f for 1 year now and we’re supposed to be moving in together soon. everything seemed to be going good but i found out she’s still really close with her ex. they were together for like 4 years.

shes called him multiple times a week, sometimes late at night. has definitely drunk called him a few times too. they send each other pics (mostly of the dog they used to have together) and she’s asked him if he’s dating. also apparently she’s told him she misses him sometimes. She also initiates every phone call and text

she said it’s nothing and they’re just friends now but idk. she also asked him while drunk if she could come over to cuddle not that long ago. and asked to see his face on video. Has drunk called him a lot in the past few months

meanwhile she says she’s all in with me and that she’s ready to build a future. i haven’t brought it up too much because i don’t want to seem controlling or jealous but something about it feels off. Even today i saw they were on the phone for 58 minutes

What would you guys do? Salvageable?
