Would you think this is suspicious ?

So my boyfriend and I are going on our third year of our relationship , and where pretty comfortable w each other and trust each other .

But recently he’s started to go to the movies alone and idk if that should be something suspicious or not ? My best friend insists it’s suspicious lmao . Am i crazy to not really worry ? Or should I be ?

Lately he’s been unhappy with his job and he feels stuck in a rut i noticed , so I’m assuming maybe he’s just trying to stay distracted ? Idk is it weird if my boyfriend goes to the movies alone ?

I know he would ask me to come if I was available but his day off I’m at university or at my internship . He goes every other Tuesday bc movies are only 5$

I trust him but my friend got me feeling some type of way ( I’m an anxious person ) so idk if I should worry ? Should I ? Would you be suspicious if your man started going to the movies alone ?
