I've been going out with my boyfriend for nearly 4 years. He has 2 boys (16 & 13) with his ex wife. He goes away once or twice a year with them but I'm still not invited to join. My boyfriend & I have never been away on holiday together apart from a weekend away. The holidays are usually quite local, to the coast, camping, etc. which I would love. He is now planning a trip abroad and asked if I would be interested but is now coming up with excuses about costs & having to pay for an extra room for me and because he's left it too late, I may not be able to get leave from work at such short notice. They are currently away on their regular holiday which he only told me about 2 days before they left. Am I right to feel a bit left out/upset? I love that he’s a great dad & he spends every day with his kids which I absolutely encourage. Just feel sad as I would love to go away with him on a proper holiday. Would appreciate any advice.
