Parents are stereotypically much more concerned about who their daughter is dating than who their son is dating. I agree with the above comments that they are not particularly enamoured with your bf because he is 1.) slightly older and 2.) not in college, and the general view of people not in college is that they are lazy and potentially a bad influence on their partner, in this case you, a pleasant, college going girl.

Just ask them WHY they don't like him and they will give you those reasons and try to dismiss it but tell them that you are in college, not high school anymore, and you are old enough to be making your own decisions in life, whether they are good ideas or bad, and in this case you have used your mature, rational judgement to decide that this particular relationship is good for you. They are concerned parents so will likely continue to press their opinions, but just keep asking why. Electricians can earn LOADS of money, especially if they start up their own firm, and farming is an enjoyable, natural and also lucrative career prospect.

Anyway, looking that far into the future is ridiculous, you're at college and have been dating 1.5 months, who's looking into careers at this point?! it's not as if you're getting married is it.

You need to have experience of dating who you want from your judgement so in future you will have an accurate compass pertaining to who is a douchebag and who is genuinely worth dating - and this guy seems nice, you said it yourself.

Any further problems, just message me, I will be happy to help.

Just talk to them about it, don't let them disallow you from seeing him without a fight!

Much love, and good luck
