BF of 3 years wants to become personal trainer 🤨

So my boyfriend of 3 years (we mid 20’s) has a degree in marketing at a good uni and very intelligent man. We’ve had our ups & downs as every relationship does. But in the last 5 months we’ve just learnt to understand each other and appreciate each other.

In the last 6 months or so he’s been really struggling to find a job. He doesn’t have any work experience making people wanting to hire him very difficult. He’s been very low in himself with not having a job or a purpose and ive been there for him and kept him motivated and all!

Tonight he tells me he wants todo a personal training course. He loves his fitness and being active and healthy. And would actually be good for him. But..... I’ve dated a personal trainer before and he knows how bad that went because of mostly female clientele he had and how close physically and mentally it was with them. I ended that dating time very quickly because of it as he never knew how to say no to a girl who was obviously flirting with him.

Now here’s the thing, in the past my boyfriend hasn’t properly put a women in her place when being to forward even after him saying he has a girlfriend. Now I’m not worried about my looks or any of that, I’m fit, I’m healthy, run a good business. But I know the road this kind of job leads to.

And im worried for his sake it would be Taking him off his focus on business and growing networks and all. Business, marketing has always been his thing but it seems lately he is just doing little things which aren’t contributing to what he actually wants. He isn’t a go getter sadly and I am. But yeah tonight has really put me in a odd mood. I want to support him and encourage him in anything he wants todo, but personal training..... and. 3 year relationship. Really not to sure and think it could lead to more harm than good.

I told him how I feel and obviously with the guy I dated before him being a personal trainer and all. I said I will always support you but I just needed to address these things while we are on the topic.

And his response was.

“Yeah fair enough xxxxxxxx

I understand your concern xxx

But yeah it's something I'd like to do and think it would be beneficial for me xxxxx “

Which I agree but the whole being up close and personal with clientele isn’t exactly calming my mind.

A little back story I grew up with a dad who had a different girl in the house every 2 months or every month sometimes. Mum was left with serious depression and me and my sister just not great with relationships with growing up with that. And now my boyfriend wants todo this and expect me to be okay with being around all these women, when he hasn’t exactly shown he can decline a women. Like it has been a almost break up factor for me in the past. But we did couple counselling and moved past it but I can’t forget it and this potential opportunity does bring up those past memories.

(He hasn’t cheated, no kiss or sex with other chicks or anything) but yeah just not particularly comfortable and idk what to think really. Needed to come on here and rant a bit.

Help. Please ❤️
