My boyfriend makes some strange comments towards my friends or am I being insecure?

So I have a lovely boyfriend that I’ve been dating for a year now. We are long distance and comes every month once or twice to see me. Since he lives with his parents it’s quite hard for me to go there constantly but I live alone so it’s just better.

I’m his first long term girlfriend, (I have been cheated on before with an ex friend by the way) once he came he met my friends and one of them likes going to the gym and he does too he was asking her, her routine and she just said she casually does some here and there and then he responded “I can send you a personalised workout routine” the conversation was bit flirty and I came back extremely upset and he realised it and apologised to me a lot. He does try to set these friends up with his but they live in a different city.

Recently he got into poker and I don’t want to learn cos I have quite an addictive personality so later he asks me if my friends want to learn. I responded vaguely saying no no I don’t and he responds your friends ask them, I said they don’t play and he’s like well neither did I.

Am I just being insecure or are these comments genuinely sounding weird?
