husband told his friend he can’t have girl friends because he gets too “emotionally attached “

so I just found this out from the friends girlfriend last night. my husband had said this about two years ago (while I was pregnant and we were engaged) he’s had many girl friends over the years, most have been couples that we’re both friends with but there are two ladies that work at the office at good place of work that need to text and call him often (as in multiple times a day) and the most resent one gives me such a bad gut feeling. she’s pretty, she’s fit, she’s married but her husband is sooo controlling. (this is not exactly relevant I guess lol) i’m not sure why i feel like this but i’ve had this feeling even before i found out what he said. but he spends HOURS a day at the office, i know he’s got quite a bit of paperwork to do but it seems excessive, and he can do it from his phone so it’s not like he has to do it there all the time. we’ve been together for 7 years.

I don’t want to leave him just because of this one comment, but it really makes me wonder, him and the new girl have been getting “close” as in they are basically in constant contact all day for work and she’s at the office the whole time he’s there. I brought it up and he just told me to stop making problems. i’m not sure what to do

also to add: I don’t go through his phone, but I did she a text pop up, we had a halloween party this weekend and we had invited his phone work group (her included) and she already had plans and ahe texted a long paragraph saying they she was so sorry she couldn’t come but it looked like we all had fun and a good turn out so he “must not have missed their presence too much“ idk it just seems a bit flirty to me, or that she was trying to get him to say he missed her being there?

tell me if i’m crazy or overthinking pleeease, we’ve had such a hard past two years because we had back to back babies and have been in the “roommate” stage for so long i feel like😭

edit @realist- i’m not mad he’s at work😂 it’s just weird because before his place of work had an office at all, he did not have HOURS of “paperwork” every single day, but now that they have an office he sits there for literally hours a day and still comes home to deal with work. he’s not any more busy than when he started.
