He still has a Polish girlfriend, but he says he is no longer in love with her and is only with her because they are building a house together in Poland.
Run for the hills girl! If he has a Polish girlfriend and is building a house with her in Poland it seems very likely he will make her his Polish wife and live with her in their newly built house!
Am I getting played here, and I should get out before I get hurt?
Answer: Yes you are but you already know it, don't you?
you are just a bit of fun on the side to him and the sooner you realise that and move on, the better.
Truer words were never spoken. He will play with you gillyt because he is away from home and he needs a cuddle or more. Sorry, but that's how it is.
