Search Results: dinner with a girl and her boyfriend

Me and my boyfriend been together for over 1 year now
he's the first one to say "i love you"
He first said it 4 months into our relationship
I first said it 10 months into our relationship
Anyway, so whenever we are together, we cuddle/hug each other and he would say "i love you" and kisses me on the forehead
He says it more than 5 times
Like he would hug me tight and say "i love you"
And then we would talk about something
And then it gets quiet and he says "i love you" again and kisses me on forehead or cheek
He calls me every night before we go sleep and he ask about my day and stuff, and sometimes he would drive to my place at night randomly just to see me
He makes sure we spend time together on weekend (e. g. going out to dinner and movies, staying at his, etc)
He holds my hand/hugs me in public
Etc etc
Guys, do you think he means it?
Do guys really mean it if they say "i love you" often and then kisses the girl on forehead and/or cheek?

First off me and my boyfriend been together for 1 year and 2 months
This is both our longest relationship
My boyfriend's first relationship was 4 years ago and was with this girl he works with - she was his first girlfriend and first girl he had sex with
They dated for 6 months until she left him for another guy
3 years later, he got into another relationship with this other girl and dated for 4 months
They broke up coz she was using him for money
Then 2 months later, he met me and we started dating
During our relationship, I go out a lot with my group of friends to clubbing, dinner, concert, house parties, etc
I've never invited him because he doesn't like clubbing or partying or loud music
Whenever I told him, im going.. he will say "okay, have fun"
I asked him "do you not care if i go clubbing and all?"
He has told me "nah you can go. I trust you. You know what? you're the only girl I've dated that I trust. The other girls I've dated, when they go out, I always have this question in the back of my mind "what are they doing?" Or "are they cheating on me?".. but when it comes to you, I never questioned your intentions. I know you will not do anything stupid."
And i asked "how?"
He said "coz we have been together for over a year. I know your personality now"
Does he trust me or dont care?
Does it seem genuine?
How does he go from not trusting the other girls he dated to actually trusting me?
When i do go clubbing, he does make sure he calls me the next morning to see where I am and see if im okay and talk about it and stuff

How do I know if my boyfriend is interested in someone at his workplace?
Would he still call me everyday just to talk before we sleep?
Would he still take me out on weekends (movie, dinner, staying over at his after for whole night)?
Would he still always hug and kisses me often whenever he sees me?
Would he still have sex with me multiple times?
Would he still upload pictures of us on his social media (fb, instagram, etc) and putting captions "with my girl"?
Or would he do the opposite of those things?

So few months ago, my boyfriend told me about this girl at his work.
He told me that she got dumped by her boyfriend (of 8 years)
Anyway, so a week later, we bumped into her at the mall and he introduced us.
She already knows im his girlfriend
She would be like "how are u? Nice to meet u"
But anyway, everyone at his workplace knows im his girlfriend since he always post pictures of us on his facebook and instagram and puts on public
And he put captions like "with my pretty girl" and "my other half"
He even invited me to his co-workers dinner party last week and never left my side - he kept hugging me and putting his arm around me, etc
She wasn't there but we all took photos together and in every photo, he would always be beside me and close to me
The girls that took the photos put the photos on facebook and obviously that girl seen it cos she liked the photos
So anyway, that same girl that got dumped by her boyfriend... recently she has been liking all my boyfriend's photos
Everytime he uploads a new photo of himself, she likes it
On facebook and instagram
But she does also always like our photos (me and my bf)
I can't access her instagram cos its on private but i can see some pictures on her facebook
He likes few pictures of hers as well on facebook
I confronted him and he said "so what? she's a friend at work. I like all my friends photos. Even the ladies that are married. Even the guys at work. Its just a like. We dont talk outside work"
Is she interested?
Is he interested?
Or am i overthinking it?
